Answer: 32
Step-by-step explanation:
2^2 is 4
2^-3 = 1/8
and 4/1/8 is 32
-3x-2y=30
-2y=3x+30
y=-3/2x-15
the answer is y=-3/2x-15
Answer:
x ≈ 8.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos41° =
=
= 
Multiply both sides by 11
11 × cos41° = x, thus
x ≈ 8.3 ( to the nearest tenth )
