Step-by-step explanation:
-0.4(3*4-2)+2*4+4/3
-0.4*10+2*4+4/3
-4+8+4/3
4+4/3

Ok, so you know that we can't divide fractions no matter what. The first thing you do is keep the first fraction, then change the divide sign to multiplication ( opposite of division is multi. ) and finallly flip the last fraction to 7/1 .
Here's a video to help you understand that method more ...

The answer ends up as 6.53333333333
Hope this helps !
Volume=hpir^2
d/2=r, 24/2=12=r
h=40
v=40pi12²
v=40pi144
v=5760pi cubic inches per section
So the equation is 2x + y = 9
you want to solve the equation so that y is on one side. in order to do this you need to subtract 2x from BOTH sides to get y by itself.
after, you should get y = 9 - 2x
