Answer:

Step-by-step explanation:

Well, first of all the two angles listed on the diagram are alternate exterior angles. Since they are alt exterior angles, they must be congruent to one another. Congruent means: equal or the same.

1. So first I am going to form an equation.

(9x - 5) = (7x - 25)

2. Then I am going to solve.

(9x - 5) = (7x - 25)

3. First, I am going to add 5 from both sides and solve.

(9x - 5) = (7x - 25)

+5 +5

--------------------------

9x = 7x - 30

4. Now I am going to subtract 7x from both sides.

9x = 7x - 30

- 7x -7x

---------------------

2x = 30

5. I am going to divide 2 from both sides, thus making x = 15

2x - 30

÷ 2 ÷ 2

--------------

x = 15 ( This is x, now all you have to do is plug this into each identified angle.

So, the first identified angle is 130 degrees

The second one is also 130 degrees.

Remember, they are congruent so they have the same number (degrees

ryzh [129]

Answer:

$104

Step-by-step explanation:

First, convert 60% to a decimal.

60% = 0.6

Now, multiply the cost to buy the camera ($65) by the decimal.

$65 × 0.6 = $39

Now, add this amount to the amount it cost to buy the camera.

$65 + $39 = $104

The selling price for the camera will be $104.

A rectangular vegetable patch has a perimeter of 36 meters and an area of 80 square meters. What are the dimensions of the veget

hjlf

Answer: 5 and 4

Step-by-step explanation:

Perimeter = 2 ( L + W)

18 = 2(L + W) divide through by 2

9 = L + W

9 - L = W

Area = L * W

20 = L (9 - L)

20 = 9L - L^2

L^2 - 9L + 20 = 0 factor

(L - 5) (L - 4) = 0

Set both factors to 0 and solve for L

L = 5 and L = 4
