Answer:
x=12
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
5x+8x+2x =180
Combine like terms
15x = 180
Divide by 15 on each side
15x/15 =180/15
x=12
The answer is d: 16y^6/x^2
X - the number of five dollar bills
y - the number of one dollar bills
She has 18 bills in total.

She has $62.

Set both expressions equal to each other:

She has 11 five dollar bills and 7 one dollar bills.
