Answer:
X equals 45
Step-by-step explanation:
The angle all together is 180 degrees so if you do 180 minus 45 you get 135. Now since x is being multiplied by 3 you divide 135 by 3. This is 45. So x is equal to 35. hopefully that made sense. :)
Answer:
Step-by-step explanation:

Answer:
Circumference of the pizza is 50.3 ft.
Step-by-step explanation:
Circumference formula: 
<em><u>To find circumference:</u></em>
<em><u /></em>
<em><u /></em>
Then,

After that,

Then, round to the nearest tenth:

7x + 5y = 19
<u>-7x - 2y = -16</u>
<u>3y</u> = <u>3</u>
3 3
y = 1
7x + 5y = 19
7x + 5(1) = 19
7x + 5 = 19
<u> -5 - 5</u>
<u>7x</u> = <u>14</u>
7 7
x = 2
(x, y) = (2, 1)
The method would be a elimination method (the answer is C).
