Answer:
-3q+3
Step-by-step explanation:
Distance = rate*time
convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs
Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.
We know the time we know the speed, Next
distance that Fritz drive =

distance the train travel =

The question: Assume that the train travels the same distance as the car
==>

==>

Now we know that Fritz drive at 45 mph,
distance =
Answer:8x+4w
Step-by-step explanation:
So the question is
3x+4w+7x-2x
We take the variables that are the same which are
3x
7x
-2x
We add all of these together
3x+7x+(-2x)=8x
8x is our answer, so we take 8x and add 4w to it
8x+4w
This is the final answer, because there is nothing else left to do
Answer:
1
Step-by-step explanation:
4(-x+4)=12
first is to open the bracket giving u
-4x+16=12
since 16 is adding where it is when takrn to the other side it will be subtracting giving u
-4x=12-16
-4x=-4
x= -4/-4
x=1
