Answer:
C
Step-by-step explanation:
D. 4 nickels.
This is because when she has 4 nickels that equals 20 cents. And that means that the rest are dimes. So a dollar worth of dimes would be ten dimes. and Ten dimes and 4 nickels equal 14 coins and $1.20
You can skip 4 in that equation and you'll be left with 2x+12=0, which gives you 2x=-12 and finally, x=-6
the answer is 17.68 kilometers <span>10.98 miles</span>
