Am I correct for the value of x

Answer:

-3

Step-by-step explanation:

-3w-2p=-21+18=-3

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

Answer: Each piece would be 3/4 feet long

Step-by-step explanation:

If the piece of  lumber is 2 1/4 ft long, and it is cut into 3 pieces then divide

2 1/4 by 3 to find out how long each piece of cut wood would be.

2 1/4  is the same as 9/4

[tex]\frac{9}{4} / \frac{3}{1}[/tex] = 9/12  which also simplifies to  3/4

a - b= 2

Step-by-step explanation:

expanding the brackets

we have 15x^2+13x+2

a= 15 b= 13

thus, a-b =15-13

=2

The value of a - b if,  (3x + 2) (5x + 1) = ax² + bx + 2 is 2 i.e a - b = 2.

At least two numbers or variables, one or more arithmetic operations, and a statement are all required components of a mathematical expression. The term "expression" or "mathematical expression" refers to a finite collection of symbols that are well-formed in line with context-dependent criteria.

Given:

(3x + 2) (5x + 1) = ax² + bx + 2

Write the left term of the equation in the format of the right term,

3x (5x + 1) + 2(5x + 1)

15x² + 3x + 10x + 2

15x² + 13x + 2

Compare the above equation to ax² + bx + 2,

a = 15 and b = 13

Calculate the value of a - b as shown below,

a - b = 15 - 13

a - b = 2

Answer: 1 hand = 0.22... cubits.

Step-by-step explanation:

We want to write the relation between hands and cubits.

We know that there are 9 hands in 2 cubits.

So we can write:

9 hands  = 2 cubits.

Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).

Then we can divide by 9 in both sides of the equality.

(9 hands)/9 = (2 cubits)/9

1 hand = 0.22... cubits.

Answer:

22.5 hands = 3 paces

Answer:

(-6,8)

Step-by-step explanation:

By reading the question you can determine that point E is to the east, or the right, of point F by 9 units. This ultimately means you must subtract 9 units on the horizontal (x-axis) in order to get to point F.

The perimeter of the triangle is 36 units.

The distance between two points A(x₁, y₁) and B(x₂, y₂) is given by:

[tex]AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

The coordinate of the triangle is A(0, 0), B(10, 0) and C(5, 12). Hence:

AB = 10 units

[tex]BC=AC=\sqrt{(5-0)^2+(12-0)^2}=13\ units[/tex]

Perimeter of triangle = AB + BC + AC = 10 + 13 + 13 = 36 units

The perimeter of the triangle is 36 units.

Answer:

50

Step-by-step explanation:

Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.

So:

[tex]XM=MY[/tex]

The entire length of the segment (XY) is:

[tex]XY=XM+MY[/tex]

We know that XM is equivalent to MY. Substitute MY for XM:

[tex]XY=MY+MY[/tex]

Combine like terms;

[tex]XY=2MY[/tex]

We are told that YM (or MY) is 25. So:

[tex]XY=2(25)[/tex]

Multiply:

[tex]XY=50[/tex]

So, the length of XY is 50.

And we're done!

50?

2x + 5 = 25

x = 10 so 2(10) + 5 = 25

25 + 25 = 50

Answer:

[tex]\huge\boxed{\sf x = -7}[/tex]

Step-by-step explanation:

Let the number be x

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

Given that it equals 24

So, the given condition is:

3(x+15) = 24

Resolving Parenthesis

3x + 45 = 24

Subtracting 45 to both sides

3x = 24 - 45

3x = -21

Dividing both sides by 3

x = -7

Cost of the strawberry will be $0.31 per ounce.

   Given in the question,

We can write the cost as [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}[/tex].

Since, 1 pound = 16 ounces

To convert the cost of the strawberry in dollars per ounce, multiply the price by the conversion factor [tex]\frac{1\text{ Pound}}{16\text{ Ounces}}[/tex].

So the cost of strawberry = [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}\times \frac{1\text{ Pound}}{16\text{ Ounces}}=0.31\text{ Dollars per ounce}[/tex]

    Therefore, cost of the strawberry will be $0.31 per ounce.

Step-by-step explanation:

sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] → B

The equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]

From the question, we are to determine which equation should one solve to find x

Considering the right triangle in the diagram,

Opposite = x

Adjacent = 9

Hypotenuse = 10  

By SOH CAH TOA

We have that

[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]

Where θ is the angle

Then, we can write that

[tex]sin\ 26^\circ =\frac{x}{10}[/tex]

This is the equation that should be solved in order to find x

Hence, the equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]
