sam is baking cakes at her parents' bakery. she gets paid $20 a week in addition to $3 for every cake she bakes. she made $80 this week. write an equation to show how many cakes sam baked this week.
20 + 3x = 80
20 − 3x = 80
80 + 3x = 20
80 − 3x = 20

nate and maya are building model cars. maya's car is 3 inches less than 2 times the length of nate's car. the sum of the lengths of both cars is 26 inches. write an equation to determine the lengths of nate's and maya's cars.
x + 3 − 2x = 26
x + 2x = 26
2x − 3 = 26
x + 2x − 3 = 26

janet and nadia each play basketball. nadia has won twice the number of games janet has. is it possible for janet to have won 10 games if the sum of the games nadia and janet have won together is 24?
yes; janet could have won 10 games because 3x = 24.
yes; janet could have won 10 games because 2(10) is less than 24.
no; janet could not have won 10 games because 2x ≠ 24.
no; janet could not have won 10 games because 3x ≠ 24.

tisha and her academic team are working to go to state finals. they must have a certain number of points to advance. they have had three local matches and will attend a district match. district match points count for three times the number of points than local matches do. choose the equation that would tisha find how many points they need to earn in the district match, b, to advance.
b equals t over 3 minus a minus c minus d
b equals t plus a plus c plus d all over 3
b equals t minus a minus c minus d all over 3
b = 3(t − a − b − d)
