Answer:
<em>-5/4</em>
Step-by-step explanation:
7(x + 4) + 1x - 9 * 2 = -8x + -10
Distribute 7 on left side. Multiply 9 * 2 on left side.
7x + 28 + 1x - 18 = -8x + -10
Combine like terms on left side.
8x + 10 = -8x + -10
Add 8x to both sides. Subtract 10 from both sides.
16x = -20
Divide both sides by 16.
x = -20/16
Reduce the fraction.
x = -5/4
Answer:
As described in picture:
RPS = 5x + 34
QPR = 8x + 15
RPS +QPR = QPS = 88
=>5x + 34 + 8x + 15 = 88
=> 13x + 49 = 88
=> 13x = 39
=> x = 3
=> RPS = 5 x 3 + 34 = 15 + 34 = 49 deg
Hope this helps!
