Answer:

x = 33

Step-by-step explanation:

(x + 13) + (4x + 2) = 180

x + 13 + 4x + 2 = 180

5x + 15 = 180

5x = 180 - 15

5x = 165

x = 165/5

x = 33

Check:

(x + 13) + (4x + 2) = 180

(33 + 13) + 4(33) + 2 = 180

46 + 132 + 2 = 180

46 + 134 = 180

Find the midpoint of the line segment with the given endpoints. (-3,-7) and (3,0)

Crank

The coordinates of the midpoint:
$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$
x₁,y₁ - the coordinates of one endpoint
x₂,y₂ - the coordinates of the other endpoint

$(-3,-7) \\
x_1=-3 \\ y_1=-7 \\ \\
(3,0) \\
x_2=3 \\ y_2=0 \\ \\
\frac{x_1+x_2}{2}=\frac{-3+3}{2}=\frac{0}{2}=0 \\ \\
\frac{y_1+y_2}{2}=\frac{-7+0}{2}=\frac{-7}{2}=-3.5 \\ \\
\boxed{(0,-3.5)} - \hbox{the midpoint}$
