Solve 4 two-step equations: 1. 2x + 12 = 4
2. -5c + 9 = -16
3. -12 = -7 + x/4
4. -n/6 + 4 = 3

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

your answer would be 12
