Answer:

\frac{1}{4}

Step-by-step explanation:

\frac{1}{2} = \frac{2}{4}  We need a common denominator before we can add.

\frac{2}{4} + \frac{-1}{4}  means the same thing as

\frac{2}{4} - \frac{1}{4} = \frac{1}{4}

Answer: \boxed{y=\frac{4}{5}x-2}

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals, so as the slope of the given line is -5/4, the slope of the perpendicular line is 4/5.

Substituting into point-slope form,

y-6=\frac{4}{5}(x-10)\\\\y-6=\frac{4}{5}x-8\\\\\boxed{y=\frac{4}{5}x-2}

Find the measurements of “x”
sammy [17]

Answer:

x = 27 \frac{1}{3}

Step-by-step explanation:

This angle is a right angle, meaning 90 degrees, as whenever it's a right angle, there's a small square on the angle which u can see at the bottom left, so:

x + 8 + 2x = 90

3x + 8 = 90

subtract 8 from both sides

3x = 82

divide by 3

x = 27 1/3
