{6, 7}

Step-by-step explanation:

Plug in each number for x

Plug in 2

2(2)-4≥8

4-4≥8

0≥8 (2 is wrong because 0 is not greater than or equal to 8)

So we can eliminate the middle ones because two are in both b and c

Plug in 6

2(6)-4≥8

12-4≥8

8≥8 (This is correct because 8 is greater than or equal to 8)

Plug in 7

2(7)-4≥8

14-4≥8

10≥8 (This is correct because 10 is greater than or equal to 8)

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.
