Answer 1

Answer:

x = 11

Step-by-step explanation:

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Angle ABC is an exterior angle of the triangle.

Angles D and C are its remote interior angles.

m<ABC = m<D + m<C

12x - 2 = 57 + 7x - 4

Combine like terms on the right side.

12x - 2 = 7x + 53

Subtract 7x from both sides.

5x - 2 = 53

Add 2 to both sides.

5x = 55

Divide both sides by 5.

x = 11

Answer: x = 11

Answer 2

Answer:

According to exterior angle property, one of the exterior angles of a triangle is equal to the sum of the opposite 2 interior angles.

Thus,

12x-2= 57+7x-4

= 12x = 57-4+7x

= 12x = 53+7x

= 53= 7x-12x

= 53=-5x

= 53÷-5=x

= x= 10.6

Thus x= 10.6

Camille wants to set up a hot chocolate stand to raise money. She spends $40 on
hot chocolate and $0.25 for each paper cup. She uses the equation y=0.25x+40
to keep track of her spending. If Camille has $60 in donations to spend, what is
the maximum number of paper cups she can buy?

Answers

[tex]y = 0.25x + 40[/tex]

[tex]60 = 0.25x + 40[/tex]

[tex]60 - 40 = 0.25x + 40 - 40[/tex]

[tex]20 = 0.25x[/tex]

[tex] \frac{20}{0.25} = \frac{0.25x}{0.25} [/tex]

[tex]80 = x[/tex]

She can buy a maximum of 80 cups.

The area of a parallelogram is 8x^2+2x-6 and it's height is 2x+2. What is the base of the parallelogram?

Answers

Answer:

4x - 6

Step-by-step explanation:

Remember the formula for finding the area of a parallelogram;[tex](base)*(height)=(area)[/tex]

Manipulate the equation such that it is solved for the base;

[tex](base)=\frac{(area)}{(height)}[/tex]

So the equation that needs to be solved is;

[tex]\frac{(8x^{2} + 2x - 6 )}{(2x + 2)}[/tex]

Set up the division problem and solve;

_____4x - 6___

[tex]2x + 2[/tex] | [tex]8x^{2} + 2x - 6[/tex]

[tex]-(8x^{2}+8x)[/tex]

The answer is (2,6)
X:2
Y:6

Answer:

x = 2

y = 6

Step-by-step explanation:

We have a system of equations and are asked to solve for x and y.

y = -2x + 10

y = 3x

Since both equations start with y, we can subtitute.

3x = -2x + 10

Solve for x :

Add 2x to both sides :

5x = 10

Divide 5 from both sides :

x = 2

Now substitute x in the second equation because it's more easier :

y = 3(2)

3(2)

y = 6

Divide 2m in the ratio 9-1

Answers

Answer:

Step-by-step explanation:

First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.

To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.

If you have $32 and you want to see how many bulbs of elephant garlic you want to buy if four bulbs costs $8 , you first need to see how many $8 can fit into $32 . Thus, divide 32 by 8 . Now that you know $8 can fit into $32 four times, multiply 4 by 4bulbs , since there are four bulbs per $8 .

1. Rewrite in slope-intercept form. *
- 7x + 2y = 8

Answers

Answer:

y = [tex]\frac{7}{2}[/tex] x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 7x + 2y = 8 ( add 7x to both sides )

2y = 7x + 8 ( divide all 3 terms by 2 )

y = [tex]\frac{7}{2}[/tex] x + 4 ← in slope- intercept form
