Which question can be answered by using the equation 5x = 150?

Question

A: Leslie must divide 150 pieces of candy equally among 5 bags. How many pieces, x, will each bag hold?

B: Mario will spit 30 garden plots. how many plants, x, will each plot hold.

C: Nel wants to run 30 miles over the next 5 days. How many miles, x, will she run during that time?

D: Omar plans to sell 150 calendars for a fundraiser in the next 30 days. How many calendars, x, must he sell each day to reach his goal.

Answer 1

5x = 150 means 5 times some number equals 150. Which questions ask for that?

 

A: if you have 5 bags and each holds x pieces, that could be represented as 5x, and that is supposed to equal 150.

So 5x = 150 does fit.

 

B: Here you just have 30 garden plots and no further information. At best, we can represent the total number of plants as 30x, where x is the number of plants per plot.

 

C: 30 miles over 5 days equals how many miles she runs in that time: x=30. The question could have been:

if Nel runs 30 miles per day over 5 days how many miles does she run in all (30*5 = x), or

if she runs the same number of miles everyday for 5 days how many miles does she run per day (5x = 30).

 

D. 30 days times x calendars per day: 30x = 150.
