Multiply x times -2 then times the second number times -1
Answer:
If L is the rate per hour, then the time required to leak 1 gallon is (1/L) hr.
Step-by-step explanation:
Let the rate of leak be L gal/hr. Dividing "1 gallon" by "L gal/hr" results in (1/L) hr.
So 5 red cars
1/3 of all cars are red
therefor
5=1/3 of all cars
'of' means multply
5=1/3 times all cars
multiply both sides by 3
15=all cars
how many are left
basically how many are NOT red
15=all
red=5
all-red=others
15-5=others=10
10 cars are left
