What is the measure of x

Answers

Answer 1

answer: 156

explanation: just add the interior angles to get the exterior

Answer 2

Answer:

156°

Step-by-step explanation:

the total internal angle of a triangle in 180°
so,

180 - (85 + 71)
= 24°

this is the internal angle, to find the external angle subtract this value from 180
so,

180 - 24
= 156° (answer)

Answers

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°

Answers

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

The area of the painting is 60 square inchesThe area of the frame is 60.25 square inches

How to determine the area of the painting

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

How to determine the area of the frame

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

Which describes the slope of the line in the graph?
A)
zero
B)
positive
negative
D)
undefined

Answers

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

Iris paid $120.00 for a winter coat. She saved
25% off the original price.
What was the original price of the coat?

Answers

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.

What is a percentage?

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.

The variables y and x have a proportional relationship, and y = 7 when x = 2. What is the value of y when x = 5? Enter your answer as a decimal in the box.

Answers

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

Answers

Answer:

x = 49/5 (fraction)

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
