Question

7 A total of 340 gallons of oil is divided between two tanks. If at least half of the oil is pumped into the first tank, which number line represents that possible amount of oil in the second tank? (A 400 100 200 300 B 300 400 200 100 tot 200 300 400 100 O HH 300 400 100 200

Answer 1

Half of 340 gallons is:

$170\text{ gallons.}$

Let x represent the amount of oil in the second tank, we know that at least 170 gallons were pumped into the first tank, therefore, at most the other half is in the second tank:

$x\ge170.$

Answer: The above inequality in the number line is represented as follows:
