Ok, so first this is a system. You have:
8x+12y=3200
And
X+y=300.
That means y= -X + 300.
If you replace "y" in the first equation with -X+300, it would be 8x+12(-X+300)=3200.
If you simplify that, X will be equal to 100. Now go back to the second equation, which is X+y= 300.
Now that you know X is 100, you can subtract it from 300 to find y.
So,
X=100 and y=200!
Hope this helps!!!
Answer:
Volume of the solid figure = 1131 cubic inches
Step-by-step explanation:
Volume of solid figure = Volume of half cylindrical prism + Volume of the rectangular prism
Volume of half cylindrical prism =
=
= 339.29 cubic inch.
Volume of the rectangular prism = (length × width × height)
= 11 × 6 × 12
= 792 cubic inches
Volume of the solid figure = 339.29 + 792
= 1131.29
≈ 1131 cubic inches

Answer:
D, B, C, A
Step-by-step explanation:
Solve the equations by combining like terms, isolating the variable, and dividing the equation by the coefficient of the variable.
Doing this, the first equation should be 2, the second equation should be -2, the third equation should be -1, and the last equation should be -6.
Then, we can order them.
