Answer:
D. 68+(6x+4)=180
x = 18
Step-by-step explanation:
"Supplementary angles" are angles that add up to 180°
So we add the twi angles 68+(6x+4) and that equals to 180°.
68 + 6x + 4 = 180
add 68 and 4
72 + 6x = 180
subtract 72.
6x = 108
divide by 6.
x = 18
Hey there! :D
He planted 48 trees per acre. Ignore the '3 types of trees' part. I think the question is trying to confuse you. Multiply 48 by 22.
48*22= 1056
The farmer has planted 1056 trees.
I hope this helps!

Answer:
x = 3
y = -5
Step-by-step explanation:
5x+2y= 5 equation 1
3х - у = 14 equation 2
using equation 2 we have:
3x - 14 = y equation 3
using equation 3 in equation 1 we have:
5x + 2(3x -14) = 5
5x + 6x -28 = 5
11x = 5+28
11x = 33
x =33/11
x = 3
using equation 3 we have:
3(3) - 14 = y
y =9-14
y = -5

Answer:
200.96 ft²
Step-by-step explanation:
The question is on surface area of a closed cylinder
Formulae= SA=2 ×pi× r² + 2×pi×r×h
Where pi=3.14
SA= 2×3.14×2² + 2×3.14×2×14
SA=25.12+175.84
SA=200.96 ft²
