Because 4x2 = 8, so 4x7=28, then you times 28 by 2 which equals 56 and 8x7=56
Answer:
the answer would be 36.
Step-by-step explanation:
and here go you would get it
R(-5) = -3*(-5) - 4
R(-5) = 15 - 4
R(-5) = 11
Q(X)=3X+3
Q(11) = 3*11 + 3
Q(11) = 33 + 3
Q(11) = 36
So, (Q(R(-2) = 36
hope it is correct..
I got 27.5 for the mean
mean: you add up all the #'s and divide them my their quantity( in other words by how many numbers there are)
In your case you have 8 numbers, you add them and divide them by 8!
Hope it helps ;)

Answer:
60 miles per hour
Step-by-step explanation:
Consider the structure of the wording: "miles per hour"
The word "per" means for each. There is you clue.
Each is, one of and one of is unit measurement
So the controlling element in this question is that you need to convert the 3 hours into 1 hour.
Using ratio properties
180
3
=
x
miles
1
hour
We need to 'force' the left hand side into the same form as the right. That is: we need to convert the denominator into 1 and see what happens to the numerator.
⇒
180
÷
3
3
÷
3
=
x
1
⇒
60
1
=
x
1
So the unit rate of speed is
60
miles
per
−−−
hour
