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:
NM corresponds with DC, and the scale factor is 3
Please tell me if you dont understand. ill break it down for you
Answer:
x ≈ 34.28
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° =
=
( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x =
≈ 34.28 ( to the nearest hundredth )
