Answer:
x = 10
Step-by-step explanation:
108 = (5x + 47) + (2x + 63)
5x + 47 + 2x + 63 = 180
Simplify
7x + 110 = 180
Move all terms not containing x to the right side of the equation.
7x = 70
Divide
x = 10

Answer:
17) 288
18) $69.30
19) $56.00
20) $135.00
21) $132.00
22) $4,515
23) 6.9%
Step-by-step explanation:
17)(3 × 4) × (6 × 4) = 288
18) 18% + 8% + 100% = 126%.
$55 × 1.6 = $69.3
19) $32 × 175% = $56
20) 100% - 15% - 10% = 75%
$180 × 0.75 = $135
21) $3,300 × 0.04 = $13
22) 2.5% × 3 = 7.5%
$4,200 × 1.075 = $4,515
23) 58 × 1.069 = 62.002
