You'll need to isolate 9a on the left side of this equation
Please add 7 to both sides of the eqn, obtaining 9a = 117.

Solve for a by dividing both sides by 9: a = 117/9 = 13 (answer)

$9a-7=110$

$9a=110+7
$

$9a=117
$

$a= \dfrac{117}{9}$

$a=13$

If the endpoints of AB have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of AB?

pickupchik [31]

The midpoint, if the endpoints are (x₁,y₁) and (x₂,y₂):
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

$(9,8) \\
x_1=9 \\ y_1=8 \\ \\
(-1,-2) \\
x_2=-1 \\ y_2=-2 \\ \\
\frac{x_1+x_2}{2}=\frac{9-1}{2}=\frac{8}{2}=4 \\
\frac{y_1+y_2}{2}=\frac{8-2}{2}=\frac{6}{2}=3$

The midpoint of AB is (4,3).

Helga [31]

We have to find the area of the floor in order to know how many square meters of flooring they need.

The area of the floor is:
42 m* (39 m)= 1,638 m^(2)

They need 1,638 m^(2) of flooring.

Hope this helps~
