H= 12.4
I assume this is a rectangular prism. the formula is V=l*w*h
plug-in the known values
<span>V=3758.75 W=24.25 L=12.5
</span><span>3758.75 =24.25*12.5*H multiply terms
</span><span>3758.75=303.125H divide both sides by 303.125
12.4=H</span>
1.5x+4y=16
5x+4(-16)=16
5x-64=16
5x=80
x=16
2.3x+6y=15
-2x+3y=-3
Multiply the 2nd equation by 2
3x+6y=15
-4x+6y=-6
7x=9
x=9/7
3x+6y=15
3(9/7)+6y=15
27/7+6y=15
6y=78/7
y=78/42 or 39/21 or 13/7
3.7y = -14x + 42
<span>7y = 14 x + 14
-14x+42=14x+14
-28x=-28
x=1</span>
