Just ignore ABCD but can someone help me with E AND G plzzz

Answer:

2x - 1

Step-by-step explanation:

2x−1+2−2

=2x+−1+2+−2

Combine Like Terms:

=2x+−1+2+−2

=(2x)+(−1+2+−2)

=2x+−1

Answer:

Step-by-step explanation:

We need to add -1 to each side of this to get rid of the -1 in the equation.

2x - 1 + 2 = 2

2x + 1 = 2

We need to subtract 1 from each side.

2x = 1

x = 0.5

Checking:

2(0.5) - 1 + 2 = 2

1 - 1 = 0 + 2 = 2 (Checks out)

Answer:

3:4 and 15:20

Step-by-step explanation:

The answer is the fourth one because 3:4 and 15:20 are equivalent, so there's your answer. Hope it helps!

30=8+4(z-2)

Distribute 4 through the parentheses

30=8+4z-8

Eliminate the opposites

30=4z

Swap the sides of the equation

4z=30

Divide both sides of the equation by 4

4z÷4=30÷4

Any expression divided by itself equals 1

z=30÷4

or write the division as a fraction

z=30/4

copy the numerator and denominator of the fraction

30=2x3x5

4=2x2

Write the prime factorization of 30

Write the prime factorization of 4

30=2          x3x5

4=2x2

    2

Line up the common factors in both lists

Copy the common factors

Since there is only one common factor, the common factor 2 is also the greatest common factor

30÷2/4÷2

  2

Divide 30 and 4 by the greatest common factor 2

15/4÷2

Divide the numbers in the numerator

15/2

Divide the numbers in the denominator

15/2

The simplified expression is 15/2

That's it. hope it wasn't too hard to understand?

Answer:

A, B, C, D or simplify all of them

Step-by-step explanation:

Answer:

all 4 of them

Step-by-step explanation:

a. 29x + 92 = 29x - 11

   0x + 92 = -11

   0x ≠ -103

b. 29x + 11 =  29x - 11

   0x + 11 = -11

   0x = -22

   0 ≠ -22

c. 29x - 29 = 29x - 11

   0x = 18

   0 ≠ 18

d. 29x + 29 = 29x - 11

  0x + 29 = -11

  0x = -40

  0 ≠ 40

Answer:

C

(45+(15))/3=20

Answer:

y = 6 + x

Step-by-step explanation:

Membership fee = $6

Fee per visit = $1

Let

x = number of visits

y = Total cost

Total cost = fixed cost + variable cost

Fixed cost = Membership fee = $6

Variable cost = Fee per visit × number of visits

= $1 * x

= $x

Total cost = fixed cost + variable cost

y = $6 + $x

y = 6 + x

Answer:

n=12.5

Step-by-step explanation:

10/8=n/10

multiply the denominator and numerators 10 ad 10=100 divide by 8=12.5

Answer:

The correct calculation is 180 - 56

Step-by-step explanation:

From the question, we have DCG and DCF

looking at the diagram, we can see that both lie on a straight line and are a linear pair

So the addition of both will give 180

But DCG is 56

So;

DCF + 56 = 180

So;

DCF = 180 - 56

Answer:

[tex]cos^2\theta + sin^2\theta = 1[/tex]

Step-by-step explanation:

Given

[tex](\frac{b}{r})^2 + (\frac{a}{r})^2[/tex]

Required

Use the expression to prove a trigonometry identity

The given expression is not complete until it is written as:

[tex](\frac{b}{r})^2 + (\frac{a}{r})^2 = (\frac{r}{r})^2[/tex]

Going by the Pythagoras theorem, we can assume the following.

So, we have:

[tex]Sin\theta = \frac{a}{r}[/tex]

[tex]Cos\theta = \frac{b}{r}[/tex]

Having said that:

The expression can be further simplified as:

[tex](\frac{b}{r})^2 + (\frac{a}{r})^2 = 1[/tex]

Substitute values for sin and cos

[tex](\frac{b}{r})^2 + (\frac{a}{r})^2 = 1[/tex] becomes

[tex]cos^2\theta + sin^2\theta = 1[/tex]

Step-by-step explanation:

Kindly find attached a screenshot of the price list of some cars from motor 1 .com since you did not provide any in the question, and let us assume it is the same as what is available at a dealership near you.

From the list, since you don't have enough money in your account to buy a car, I will say you should get a 2017 Nissan Versa for $11,990

and 25% of  $11,990 is

(25/100)* 11,990

0.25* 11,990

$2997.5

So you can make a down payment of $2997.5

and pay the remainder of $8992.5 later

Answer:

400 square meters

Step-by-step explanation:

We can first solve this problem with each unit representing 1 centimeter, and then scale up at the very end. The shape that we have a parallelogram. The base is 8 cm, and the height is 2 cm. The formula for the area of a parallelogram is just [tex]bh[/tex], so the area of the parallelogram is 16 square centimeters. However, now we scale up. Since each centimeter correlates to 5 meters, each little box will correlate to 25 square meters. Therefore, [tex]16 \cdot 25 = \boxed{400}[/tex] square meters is our answer

280+35=315

315 miles in 4.5 hours

Answer:

yes it is because it is expressed in the form of a p/q

Step-by-step explanation:

If a number is expressed in the form of p/q then it is a rational number. Here p and q are integers, and q is not equal to 0. A rational number should have a numerator and denominator. Examples: 10/2, 30/3, 100/5.

so yes 10/2 is a rational number

oh and i mean yes its rational no its not irrational :)

No, it is not an irrational number.

Irrational numbers are those who cannot be turned into a fraction.

10/2 is a fraction. Therefore, it is a Rational number.

[tex]Edit:\;Also,\;if\;you\;were\;to\;make\;it\;a\;whole\;number\;then\;it\;would\;be\:5.[/tex] [tex]Which\;can\:be\;turned\;into\;5/1.[/tex]

To do so, divide the numerator (Top number) by the denominator (Bottom number).  

Answer: No.

Step-by-step explanation: It's obviously a quiz of some sort. If it's not, then why would it be timed? Please don't do this :(

Step-by-step explanation:

Answer:

[tex]\displaystyle v=46.07\ Km/h[/tex]

Step-by-step explanation:

Speed

The speed is the ratio between the distance x traveled by an object and the time t taken.

[tex]\displaystyle v=\frac{x}{t}[/tex]

The car travels x=43 Km in t=56 minutes. We are required to express the speed in Km/h. The time needs to be expressed in hours:

[tex]t = 56 / 60 = 0.933\ h[/tex]

Now apply the formula:

[tex]\boxed{\displaystyle v=\frac{43}{0.933}=46.07\ Km/h}[/tex]
