Two Step Equations TEST

A 7- inch candle burns at a rate of 2 inches an hour.  Which equations represents the relationship between y, the height of the candle in inches, and x, the number of hours the candle burns?

• y = 2x + 7
• y = 7 - 2x
• y = 2 - 7x
• y = 7x + 2

Eddie scored 27 points more than half of what Duncan scored. Eddie scored 58 points. Which equation represents the situation to find how many points Duncan scored?

• 1/2d + 27 
• d + 27 = 58
• 0.5d + 27 = 58
• 0.5d - 27 = 58

Eight less than 7 times a number is the same as 4 more than 3 times the number

• x + 3 = x
• 8 = x + 4 + 3
• 8 - 7n = 4 + 3n
• 7x - 8 = 3x + 4

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation to find out how many hours, h, they rented the Boat if the total cost was $33.

• h = 2(9) + 15
• 33 = 15h + 2
• h = 15(9) + 2
• 33 = 2h + 15
