Answer:
840mm^3
Step-by-step explanation:
V=(1/2)LWH
L=14
W=10
H=12
14*12*10=1680
Then divide by 2
840
Combine like terms so combine -2x and x which gives you x=143
For the first question x is equal to 4. You get this by adding 7x+2 and 3x and equal it to 42. And then solve algebraically so 10x+2=42
10x=40 so x equals 4
For the second question x is equal to 6.666 and y is equal to 9
You get this by getting x is to 10 as 4 is to 6 and you get y by 6 is to y as 4 is to 6
Hope this helps
40 x (80/100)
= 32
So answer will be 32
