Answer:
3 hours
Step-by-step explanation:
he washed one car in 20 minutes so 9 cars will be 20 x 9=180minutes which is 3 hours
Step-by-step explanation:
y=-2x+1 so we say (-2x+1)
we flip the equation by saying
-2x+1 -1=y+-1
-2x=y-1
Divide both sides by -2
-2÷-1 = y-1÷-2
so x=-1÷2 y=+1÷2
Answer : -4a+10
Substitute (a-3) for x
-4(a-3)-2
-4a+12-2
-4a+10 but can also be written as -2(2a-5)
