Answer:

y = 17.5

Step-by-step explanation:

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form  y/x = k or y = kx

Find the value of the constant k

we have:

y = 7 and x = 2

substitute

7/2 = k

k = 3.5

Thus, the equation is equal to

y = 3.5x

Find the value of y when  x = 5

substitute in the equation

y = 3.5(5) = 17.5  

Or we can put as:

y = 7 * 5 /2

Calculate the product or quotient: y = 35/2

Answer = 17.5

[RevyBreeze]

Answer:

y = 17.5

Step-by-step explanation:

If y is proportional to x, then:

[tex]y = kx[/tex] (for some constant k)

Given y = 7 when x = 2:

⇒ 7 = 2k

⇒ k = 3.5

Therefore, [tex]y=3.5x[/tex]

So when x = 5:

⇒ y = 3.5 x 5

⇒ y = 17.5

Answer:

Measure of each angle is 108 and 72 degrees.

Step-by-step explanation:

Let's the angle  be "n"

Supplementary angle = 180 °

n- (180-x) = 36

n - 180 + n = 36

Combine like terms

n - 180 + n = 36

2n - 180 = 36

Add 180 to both sides of the equation

2n - 180+180 = 36+180

Simplify

2n = 216

Divide both sides of the equation by the same term

2n/2 = 216/2

Simplify

n = 108

2n = 216  

Measure of each angle

1st = 108

2nd = 180-108 = 72

[RevyBreeze]

Answer:

An angle measures 36° more than the measure of its supplementary angle. What is the measure of each angle?

Step-by-step explanation:

Let's the angle  be "n"

Supplementary angle = 180 °

n- (180-x) = 36

n - 180 + n = 36

Combine like terms

n - 180 + n = 36

2n - 180 = 36

Add 180 to both sides of the equation

2n - 180+180 = 36+180

Simplify

2n = 216

Divide both sides of the equation by the same term

2n/2 = 216/2

Simplify

n = 108

2n = 216  

Measure of each angle

1st = 108

2nd = 180-108 = 72

Answer:

5(8a + 9)

Step-by-step explanation:

40 and 45 can both be divided by 5, so this is a common factor.

-> 40 divided by 5 is 8

       [] It has a variable, so it will be 8a

-> 45 divided by 5 is 9

Our final answer is 5(8a + 9)

-> To check we can multiply it out, 5 * 8a is 40a, 5 * 9 = 45

-> This works

Answer:

  23°

Step-by-step explanation:

There is not enough information given in this diagram to provide values for the marked angles. In order to solve the problem, we must assume some relation between those angles.

If they are equal, then ...

  9x -22 = 6x -7

  3x = 15 . . . . . . . . . . add 22-6x to both sides

  x = 5 . . . . . . . . divide both sides by 3

 m∠ABD = (9x -22)° = (9·5 -22)° = 23°

Answer:

C. Negative

Step-by-step explanation:

The line is not horizontal or vertical, therefore we the slope cannot be zero or undefined.

This leaves us with either positive or negative...

A positive slope goes from the lower left corner (Quadrant 3) of the graph up to the upper right (Quadrant 1).

A negative slope goes from the upper left corner (Quadrant 2) of the graph down to the lower right (Quadrant 4).

Since this line goes from the upper left corner to the lower right, it has a negative slope

Answer:

Answer:

Step-by-step explanation:

1. 43+(-56) - 78

43 - 56 - 78 = -91

2. -78 - 65 = -143

3. -19 - 4 = -23

4. -16 + 9 = -7

5. 71 + (-18)

71 - 18 = 53

Hope this helps!

Answer:

Step-by-step explanation:

43+(-56)minus 78= negative 91

43+-56= - 13    13-78= negative 91

-78 subtract 65=143 because when your in negatives it is opposite so when you subtract it is addition so what is -30 add 50=20. So what is -78 subtract 65=143

-19 subtract 4 =-23 because like I said in negatives it's opposite.

-16+9=7.

And last 71 + -18=53 because it is subtracting 18 since it is negatives.

Hope it helps :)

The area of a shape is the amount of space on the shape

From the question, the dimension of the painting is 6 inches by 10 inches

So, the area of the painting is:

Area = 6 * 10

Area = 60 square inches

Hence, the area of the painting is 60 square inches

From the question, the dimension of the picture is 9.5 inches by 13.5 inches

So, the area of the picture is:

Area = 9.5 * 13.5

Area = 128.25 square inches

The area of the frame is the difference between the area of the picture and the painting.

So, we have:

Frame = 128.25 - 60

Frame = 68.25

Hence, the area of the frame is 60.25 square inches

Addition can be defined as the process of adding two numbers. The sum of 5 and 5 is 10.

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

Given that we need to add 5 and 5. This can be simply understood with the help of an example. One hand has 5 fingers and as we need to add the 5 and 5 therefore, we need to add the number of fingers in the two hands which is equal to 10. therefore, we can write it as,

[tex]5 + 5 =10[/tex]

Hence, the sum of 5 and 5 is 10.

Step-by-step explanation:

Add and subtract the numbers: -15 + 52 =37

6x+37=11x-12

Subtract 37 on both sides:

6x+37-37=11x-12-37

Simplify:

6x=11x-49

Subtract 11x from both sides:

6x-11x=11x-49-11x

Simplify:

-5x=-49

Divide both sides by -5

-5x/-5=-49/-5

= 49/5

Answer:

$160, or answer A

Step-by-step explanation:

If 120 is 25% of the original, or 0.25 of the original(We will call it x), then 120 is 0.75x.

Form an equation like this:  0.75x=120

Turn this into fractions:  3/4x=120/1.

Divide by 3/4 on both sides.

x = 120/1 * 4/3

Simplify to get: 40/1 * 4/1

Multiply to get: 160

The original price of the coat is $160.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given. Iris paid $120 for a winter coat.

She saved 25% off the original price .

We have 4 options $160, $150, $145 and $30.

Now let $160 is the original price,

25% of 160 = 160 x 25 / 100

                  = $40

Therefore, the original price of the coat is $160.
