The answer is -21. Rule is that you follow the sign of the larger and add the opposite
The top and bottom are the same length:
5x +10 = 40

5x = 30
Divide both sides by 5:
x = 30/5
x = 6

Answer:
44
Step-by-step explanation:
Hello There!
To solve this one all we have to do is plug in 5 for a
so
9(5)-7+6
9x4=45
45-7=38
38+6=44
so when a=5 the value of the expression is 44
Answer:
135°
Step-by-step explanation:
To convert from radian measure to degree measure
degree measure = radian measure ×
, so
degree =
× ![\frac{180}{\pi }](https://tex.z-dn.net/?f=%5Cfrac%7B180%7D%7B%5Cpi%20%7D)
Cancel π on numerator/denominator and 4, 180 by 4, leaving
degree = 3 × 45 = 135°
