Subtraction:

The act of deleting items from a collection is represented by subtraction. Subtraction is denoted by the minus sign. For instance, supposing there are nine oranges stacked together (as indicated in the above image), four oranges are taken out and put in a basket, leaving nine – four oranges, or five oranges, in the stack. Therefore, 9 minus 4 equals 5, or the difference between 9 and 4.

Different kinds of numbers can also use subtraction, which is not just applicable to natural numbers.

The symbol for subtraction is the letter "-". The three numerical elements that make up the subtraction operation are the minuend, the subtrahend, and the difference.

The minuend, from which we subtract another number, is the first number in a subtraction process.

v/7 + 7.1 = -4.1 solve for v

Answers

Subtract 7.1 from both sides
V/7=-11.2

Multiply the answer by 7
V=-78.4
hello!

Answer:

v = -78.4

Explanation:

To solve this, we’re going to need “v” left on one side on its own.

To do this, first get rid of +7.1 by taking it away from both sides of the equation. This leaves v/7 = -11.2

Then multiply by 7 on both sides to get rid of the “divide by 7”. This leaves “v = -11.2 multiplied by 7”.

Multiplying this out gives v = -78.4.

Sal has already finished startfraction 5 over 9 endfraction of the 45 math problems he was assigned.

Answers

The correct expression to determine the amount of time is 45 times startfraction 4 over 9 endfraction times three-fifths.

Sal has finished = 5/9 of 45 maths problems

So, the remaining number of maths problems = 1 - 5/9

The remaining number of maths problem = (9 - 5)/9

The remaining number of maths problem = 4/9 of 45

Amount of time to solve 1 problem = 3/5 of a minute

Amount of time to solve 4/9 problems = 45×4/9 × 3/5 of a minute.

Hence, 45 times startfraction 4 over 9 endfraction times three-fifths is the correct expression to find the time.

The standard form of quadratic function is f(x) = 1(x-2)2 - 6

A quadratic function is a two-degree function. A parabola is the graph of a quadratic function. A quadratic function has the general form f(x)=ax2+bx+c, where a, b, and c are real numbers and a0. A quadratic function has the standard form f(x)=a(xh)2+k. The vertex (h,k) has the coordinates h=-b2a,k=f(h)=f(b2a).

Given points (5,3) and (2,-6)

We know that the General form of a quadratic function is

f(x) = ax2+bx+c

Standard form = a(x-h)2 + k

Here point(x,y) = (5,3) and vertex (h,k) = (2,-6)

y =  a(x-h)2 + k

3 = a(5-2)2 – 6

3 = a(3)2 – 6

3 + 6 =9a2

9= 9a2

a2 = 9/9

a2=1

a=1

Now substitute a value in standard form

f(x) = 1(x-2)2 – 6

the population of the world in 2010 was 7 billion and the annual growth rate was estimated at 1.2 percent per year. assuming that the world population follows an exponential growth model, find the projected world population in 2044. round your answer to one decimal place.

Answers

With annual growth rate of 1.2% per year, the projected world population in 2044 is 10.5 billion

The formula for the exponential growth model is:

X(t) = Xo (1 + r)^t

Where:

X(t) = value of X at time t

Xo = initial value

t = time interval

r = growth rate

Parameters given:

Xo = 7 billion = 7 x 10⁹

t = 2044 - 2010 = 34

r = 1.2% = 0.012

Hence,

X(t) =  7 x 10⁹ (1 + 0.012)³⁴

X(t) = 10.5 x 10⁹ = 10.5 billion

Therefore,

The projected world population in 2044 = 10.5 billion

The solution of the inequality is x>2 and the graph is attached below.

What is inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. When two values are compared, an inequality shows whether one is higher, lower, or simply not equal to the other.

The given inequality is 2x - (3-x) > x + 1,

Now, solving the inequality by opening the bracket,

2x - (3-x) > x + 1

[tex]2x - 3 + x > x + 1[/tex]

3x - 3 > x + 1

Subtracting x from both sides and  adding 3 on both sides,

2x > 4

x > 2

Solve this system of 3 variables with elimination. Once you eliminate 1 variable to get down to only 2, you can use Desmos but show all work/steps first.
3x − 4y + z = 2
−9x + 12y − 3z = − 6
4x − 2y − z = -16

Answers

The value of the x, y, and z for the given system of equations are; x =  -2/3, y = -1/2, and z = 1.

First, let us understand the equation:

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given the system of equations;

3x − 4y + z = 2                ...........equation 1

−9x + 12y − 3z = − 6       ...........equation 2

4x − 2y − z = -16             ...........equation 3

Add equation 1 to equation 3, we will get;

(3x − 4y + z ) + (4x − 2y − z ) =  2 -16

7x - 6y = -14  ...........equation 4

Multiply equation 3 by 3 and subtract from equation 2, we will get;

3(4x − 2y − z) - (−9x + 12y − 3z ) = -48 + 6

12x - 6y - 3z + 9x - 12y + 3z = 42

21x  - 18y = 42   ...........equation 5

Multiply equation 4 by 3 and add it to equation 4, we will get;

3(-3x + 3z) + (9x + 4z) = 5×3 - 2

-9x + 9z + 9x + 4z = 15 -2

13z = 13

z = 1

Put z = 1 in equation 5, we will get;

-3x + 3×1 = 5

-3x + 3 = 5

-3x = 5 - 3

x = -2/3

y = -1/2

Thus, the value of the x, y, and z for the given system of equations are; x =  -2/3, y = -1/2, and z = 1.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have a table below that shows the number of hours the Carrera family has been driving and the number of miles they’ve driven.  

We can find the slope of the line from the table as follows -

m = (168 - 84)/(3 - 1.5)

m = 56

Now, we can write -

y = 56x + c

84 = 56 x 1.5 + c

c = 0

So, the equation would be -

y = 56x

Therefore, the equation that best represents this relationship given in the table is y = 56x.

Answers

For the given data, 1 free download song and cost of each additional download song is $0.59 ,then total downloaded songs in $15.34 including  28 free songs is equal to 54 songs.

As given in the question,

Total free download songs is equal to 28

Let us consider variable 'x' to represent  the number of downloaded songs at the rate of $0.59

Total monthly bill of downloaded songs = $15.34

Equation formed :

0.59x = $15.34

⇒ x = 15.34 / 0.59

⇒ x = 26 songs

Total number of downloaded songs including 28 free songs

= 26 + 28

= 54 songs

Therefore, for the given data, 1 free download song and cost of each additional download song is $0.59 ,then total downloaded songs in $15.34 including  28 free songs is equal to 54 songs.

Half of A's money plus one, fifth of B's makes #100. Two
Thirds of A's money plus two-fifth of B's makes # 150.
How much money has each?

Answers

The money A has is #150 and the money B has is #125.

According to the question,

We have the following information:

Half of A's money plus one-fifth of B's makes #100. Two-thirds of A's money plus two-fifth of B's makes # 150.

So, we will convert these verbal phrases into expression.

Now, let's take the amount of A to be #x and the amount of B to be #y.

x/2 + y/5 = 100

Using the least common factor of 2 and 5:

5x+2y = 1000

5x = 1000-2y ...(1)

2x/3 + 2y/5 = 150

Adding the fractions using the least common multiple of 3 and 5:

(10x+6y)/15 = 150

Using the cross multiplication method:

10x+6y = 2250

Now, putting the value of 5x from equation 1:

2(1000-2y)+6y = 2250

2000-4y+6y = 2250

2y = 2250-2000

2y = 250

y = 250/2

y = #125

Now, putting this value of y in equation 1:

5x = 1000-2y

5x = 1000-2*125

5x = 1000-250

5x = 750

x = 750/5

x = #150

Hence, the money A has is #150 and the money B has is #125.

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 25 books and each large box can hold 35 books. A total of 15 boxes were sent which can hold 455 books altogether. Determine the number of small boxes sent and the number of large boxes sent. What theory did Heisenberg propose? 1. For the series circuit in Fig. 21.51:a. Find the value of XC for resonance.b. Determine the total impedance of the circuit at resonance.c. Find the magnitude of the current I.d. Calculate the voltages VR, VL, and VC at resonance. How are VL and VC related? How does VR compare to the applied voltage E?e. What is the quality factor of the circuit? Is it a high or low Q circuit?f. What is the power dissipated by the circuit at resonance? which part of a cell synthesesises protien what did the persians ask for as acts of submission and what did the spartans do to them During replication, the enzyme dna uses energy from atp to separate the two strands. This generates additional coiling ahead of the replication fork that is alleviated by another enzyme called dna.
