If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:
-24 ≤ 3x - 9 First add 9 on both sides
-24 + 9 ≤ 3x - 9 + 9
-15 ≤ 3x Then divide 3 on both sides to get "x" by itself
-5 ≤ x [or x ≥ -5 if you prefer "x" to be on the left side]
Answer:
∠ QRS = 100°
Step-by-step explanation:
Since RU bisects ∠ QRS , then
∠ QRU = ∠ SRU , that is
x + 10 = 50 ( subtract 10 from both sides )
x = 40 ( multiply both sides by 2 )
x = 80
Then
∠ QRU = x + 10 = 0.5 × 80 + 10 = 40 + 10 = 50°
∠ QRS = 50° + 50° = 100°
