The answer is (4x11)-7 i believe
1) 3x - 2y = -16 Subtract 3x from both sides
-2y = -3x - 16 Divide both sides by -2
y = 
x + 8
2) 9x - 7y = -7 Subtact 9x from both sides
-7y = -8x - 7 Divide both sides by -7
y = 
+ 1
3) x - 3y = 6 Subtract x from both sides
-3y = -x + 6 Divide both sides by -3
y = 
- 2
Answer:
closest option B (50.24)
Step-by-step explanation:
A=πr²
= π×4×4
=π×16
=50.265m²
Supplementary angles = 180°
so to find the supplement of a 123° angle:
180 - 123 = 57°
hope this helps and have a great day :)
