Nikki has a gift card with a beginning balance of $300. She buys several items that costs $40 each. After her purchases, she has $140 remaining on the gift card. Which equation could be used to find how many $40 items she purchased?
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)

Marty has 11 more than twice as many customers as when he started mowing lawns. He now has 73 customers. Which equation could be used to find how many customers Marty started with?
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)

Paula bought a ski jacket on sale for $6 less than half its original price. She paid $88 for the jacket. Which equation could be used to find the original price
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)

The 2nd step in a 2-step equation is always
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)

The current temperature in Smalltown is 20 degrees F. This is 6 degrees less than twice the temperature that it was six hours ago. Which equation represents this scenario?
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)

Solve (g/3) - 7 = 15
-11
2x + 11 = 73
300 - 40x = 140
2x - 6 = 20
multiply or divide the coefficient
(x/2) - 6 = 88
add or subtract the constant (single number)
