Answer:
$9 is the part, 15% is the percent, and $60 is the whole.
Step-by-step explanation:
$9 is %15 of the whole. This means $9 is the part, 15% is the percent, and the whole is the total cost of the shoes after the discount. The total cost of the shoes after the discount is 60.
2(8x - 1) + 7(x + 5) = -59 Distribute/multiply 2 into (8x - 1), and multiply 7 into (x + 5)
16x - 2 + 7x + 35 = -59 Combine like terms
23x + 33 = -59 Subtract 33 on both sides
23x = -92 Divide 23 on both sides
x = -4
[proof]
2(8x - 1) + 7(x + 5) = -59
2(8(-4) - 1) + 7(-4 + 5) = -59
2(-32 - 1) + 7(1) = -59
2(-33) + 7 = -59
-66 + 7 = -59
-59 = -59
