Answer:
$80.00
Step-by-step explanation:
12m = 120
m = 10
Therefore, 8m must equal 80.

Answer:
(-6, 9) is the solution set for given system.
Step-by-step explanation:
Given that:
3x-y=-27 ----------- eq1
4x+2y=-6 --------- eq2
Solving by combining the equations:
Dividing eq2 by 2 we get:
2x + y = -3 ------- eq3
Now add eq1 and eq3, we get:
5x = -30 (y from both equations will be cancelled out)
Dividing both sides by 5:
x = -6
Now putting value of x back in eq3:
2(-6) + y = -3
-12 + y = -3
Adding 12 on both sides:
y = -3 + 12
y = 9
So the solution set for given system is (-6, 9)

Answer:
Correct answer is: A = 8 m π
Step-by-step explanation:
In fact, it is necessary to calculate the surface of the circular ring representing the circular window frame:
It's formula:
A = (R² - r²) π where R = m + 2 and r = m - 2
A = ((m + 2)² - (m - 2)²) π = (m + 2 + m - 2) (m + 2 - m +2) π = 2m · 4 π
A = 8 m π
God with you!!!
