Answer:
18
Step-by-step explanation:
x + (x + 1) + (x + 2) = 57
x + x + 1 + x + 2 = 57
x + x + x + 1 + 2 = 57
3x + 3 = 57
3x = 57 - 3
3x = 54
x = 54/3
x = 18
First add 11 and 4 because you need to know how many he had in total 11+4=15 then divide 15 by 3 and then you have you answer 15/3=5.
There are 5 model cars in each pack.
So you would find out what number in the 9 times tables goes into 25 and there's your answer x
We are asked to express r in terms of A, P, and t.
We first divide both sides of the equation by t, which gives us

,
then, dividing both sides by P, we have

.
Swap the sides:
Finally subtracting 1 from both sides gives us

.

1
Step-by-step explanation:
If we have 2 points we can find the slope
(0,-7) and (6,-1) are two points on the line
Slope is given by
m=(y2-y1)/(x2-x1)
=(-1--7)/(6-0)
= (-1+7)/(6-0)
=6/6
=1
