Step-by-step explanation:

First 4 wheeler:

52mi -  5gal

Second 4 wheeler:

21mi - 2 gal

To compare we have to make sure everything is equal so,

5÷2 = 2.5

so,

second 4 wheeler:

21*2.5=52.5 , 2*2.5=5

52.5mi - 5gal

If M (4.2) is the midpoint of AB and A (-5, -3), find the coordinates of B.
loris [4]

Given:

M(4,2) is the midpoint of AB and A(-5, -3).

To find:

The coordinates of B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

M(4,2) is the midpoint of AB and A(-5, -3).

M=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)

(4,2)=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)

On comparing both sides, we get

4=\dfrac{-5+a}{2}

8=-5+a

8+5=a

13=a

And,

2=\dfrac{-3+b}{2}

4=-3+b

4+3=b

7=b

Therefore, the coordinates of point B are (13,7).
