Two-Step Equations
5n + 9 = 2n + 12
what is n = 1
What expression could represent the perimeter of a rectangle with a length of (20x + 8) and a width of (2x)
what is 44x +16
8y - 3 = 6y + 17
what is y = 10
On a beach trip, Lucy rents a bike from “Wheels by the Waves”, where they rent bikes for $12 plus $3 per hour. If Lucy spent $30, write an equation for how many hours (h) she rented a bike?
What is 3h + 12 = 30
6x + 5 - 2x = 3x + 26
what is x = 21
James bought a cheeseburger, fries for dinner. The cheeseburger was three times the price of the fries, and the drink and the fries were the same price. If the entire meal cost $12.50, write an equation to find the price of the cheeseburger?
What is 3x + x + x = 7.50
3x - 4 + 2x + 2 = 3x + 1
what is x = 3/2
While at the beach, Daniel buys lunch for his family from a food stand. He purchases one hot dog for $2.50 and 3 hamburgers. If he spent $13 total, write an equation to find h, the amount each hamburger cost.
what is 3h + 2.50 = 13
h = price of a hamburger
(1/2)x + 3 = 5 - (3/2)x
what is x = 1
The water temperature at the beach started at 82 degrees, and it is rising 0.6 degrees each hour. If the water temperature is now 85 degrees, write an equation to find h, the number of hours that have passed. Solve the equation.
What is 0.6x + 82 = 85
what is 5 hours
