1 julies car travels 27 miles per gallon of gassoline used. she recently travedled 324 miles. how many gallons of gasoline did her car use? im learning about algebra multiplicaion property of equality and divsion property of equality
would i write: i know i have to divide 324 / 27 = 12
but im not sure how to write out for algebra using a variable.
g/27 = 324
27 *g/27 = 324/27
g= 12 gallons. is that right?

2) a local park rents paddle boats for $5.50 per hour. you have $22.00 to spend. How many hours can you rent a boat? 22.00 / 5.50 is : 4 hrs
do i write it as:
h/5.50 = 22.00
5.50 * h/5.50 = 22.00 / 5.50
h = 4
is that right?

3) a video store charges $2.75 per day for overdue videos. You owe a late fee of $13.75. How many days overdue is the video?
