Solve equations honors

In order to solve an equation, we must get variables on side of an equation, and constants on the opposite side.

• True

• False

3r - 24= -r

• r = 6

• r = 12

Joaquin has a $50 gift card from Pizza Palace. All pizzas at Pizza Palace cost $7 each. Joaquin wants to give the driver a $5 tip for delivering the pizza. Which inequality could be used to determine the possible number of pizzas, p, he could order with his gift card, including the tip?

• 7p + 5 ≤ 50

• (7 + 5)p ≤50

• 7p + 5 ≥ 50

• 7p + 5 < 50

2a + 4 = 7 + a

• a = 1

• a = -3

• a = -1

• a = 3

At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal?

• 150x + 24 = 180 + 20x

• 150 + 24x = 180 + 20x

• 180 - 150 = 24 x + 20x

• 150 - 24x = 180 - 20x
