Julius is selling raffle tickets for $2.50 each. The prizes to be awarded cost $2,260. Which equation represents the number of raffle tickets, x, that must be sold in order to pay for the prizes?
2.50x = 2,260
x + 2.50 = 2,260
2.50 = 2,260x
The sum of a number, x, and 12 is 250. Which equation can be used to find the value of x?
12 • x = 250
250 • 12 = x
12 + 250 = x
x + 12 = 250
Mallory bought pizza and soda for a party. If she spent $12.57 on the sodas and $10.95 for each pizza, how many pizzas did she buy if her total is $89.22?
10.95x + 12.57 = 89.22
12.57x + 10.95 = 89.22
89.22x -10.95 = 12.57
12.57 + 10.95 = 89.22
Jen wants to buy a new car for $18500. She pays $2500 at signing and wants to pay $250 per month. How many months until it is paid off?
18500 + 2500 = 250x
2500 -250x = 18500
250x + 2500 = 18500
2500(250)x = 18500
Sebastian’s age is 3 times Katie’s age. 3 years ago, Sebastian and Katie’s age added together is 33. Write an equation to represent this situation. Select all that apply.
3k-6=33
(3k+3)+(k+3)=33
4k-6=33
(3k-3)+(k-3)=33
At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven. Write an equation that represents this situation.
y = x(35 + 0.75)
y = 35x + 0.75
y = 0.75x + 35
y = 0.75(x + 35)
A plant is currently 5cm tall and growing at a rate of 3cm a month. Write an equation that represents this situation.
y = 5 + 3
y = 5x + 3
y = 3x + 5
y = 3x + 5x
Natalie is a softball coach. She has a pitching private lesson with Kasey. Kasey's mom pays Natalie $11 per hour plus a $6 tip. Write an equation that represents this scenario if the total cost was $39.
11x + 6 = 39
11x - 6 = 39
11 + 6x = 39
66x = 39
Jacob collects hats. He has 6 hats already, and he collects 2 hats a week. Write an equation that represents this scenario.
y = 6x - 2
y = 6x + 2
y = 2x - 6
y = 2x + 6
How old am I if 400 reduced by 2 times my age is 244? Write an equation that represents this scenario.
2x - 400 = 244
400 – 2x = 244
400 - 244 = 2x
400 - 2 = 244x

Solve c = λν for λ
λ = c/ν
λ = ν/c
Solve for x.
1/2(x - h) = g
x = 2g-h
x = 1/2g - h
x = 2g+h
x = 1/2gh
Solve for x.
3/4(x + 2) = k
x = 4/3k - 2
x = k / 3/4
x = 4/3k + 2
