Translating Equations

Translate into an inequality: Each of your parents gave you $2, but you owe your brother $6. You need at least $18 to buy tickets to a concert on Friday. Which inequality matches this situation?

• 6 - 2x < 18

• 6 - 2 - x = -18

• 6 - 2x ≤ 18

• 2x - 6 ≥ 18

Translate into a correct inequality: You buy a ticket for $6 and $2 for each drink. If you and a friend want to get drinks, and you offer to pay, which expression would represent how much you will pay?

• 6x + 2

• 6x - 2

• 6 - 2x
