Answer:
Marco has $57.50 in total.
Step-by-step explanation:
17 x 10 = 170 quarters
170 x 0.25 = $42.50
11 x 10 = 110 dimes
110 x 0.10 = $11.00
8 x 10 = 80 nickels
80 x 0.05 = $4.00
Answer:
x = -6
Step-by-step explanation:
Distribute the 2 into the brackets:
2x + 10 = -2
leave the 2x alone on one side:
2x = -2 -10
2x = -12
divide both sides by 2:
x = -6
