Answer:
50
Step-by-step explanation:
20, 32, 41, 46, 54, 73, 81, 81
46+54= 100
100 divided by 2= 50
Answer:
x = -84, y = -58
Step-by-step explanation:
2x - 3y = 6 --- Equation 1
Equation 1×5: <em>10x</em> - 15y = 30 --- Equation 2
5x + 7y = -14 --- Equation 3
Equation 3×2: <em>10x</em> + 14y = -28 --- Equation 4
<u>I will eliminate 10x. </u>
Equation 4-2:
10x - 15y - 10x + 14y = 30-(-28)
-y = 30+28
= 58
y = -58
Substitute y =-58 into Equation 1.
2x - 3y = 6
2x - 3(-58) = 6
2x - (-174) = 6
2x + 174 = 6
Find 2x.
2x = 6-174
= -168
Find x.
x = -168 ÷ 2
x = -84
Answer:
-8
Step-by-step explanation:
4x + 2x - 4 = 4x + x - 12
6x - 4 = 5x - 12
x = -8
The formula for volume of a prism is V=l*w*h
You just have to plug in the information given to solve for V
V=4.1*5*6.9
V=141.45 cubic feet
Hope this helps!
