Question

Define a variable and write an equation for each situation. Solve each equation to answer the question.

Answer 1

Your equation is wrong

the first is suppoosed to be 3(45), you wrote 5(45) but it should be 3(45), it's 3 trips, not 5


the other part is right tho, it is 6h

so 3(45)+6h=303 is the right equation
remember, you can do anything to an equation as long as you do it to both sides

so first expand 3(45)
3(45)=135

135+6h=303
minus 135 both sides
6h=168
divide both sides by 6
h=28
