Can someone plz help me solved this problem I need help plz help me!

Both 8 gallons!

Step-by-step explanation:

Let's say we have x gallons of 25% solution and y gallons of 45% solution.

Then, obviously, x+y=16.

But how much alcohol do we have? That will be 35% of 16 = 5.6

So the second equation you can create is:

0.25x + 0.45y = 5.6

Solve these together and you have your answer.

Let's do the second one times 4 to get integers:

0.25x + 0.45y = 5.6 =>

x + 1.8y = 22.4

Combine with the first:

22.4-1.8y + y = 16

0.8y = 6.4

y = 8

so x = 16-y = 8

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

it will be a cylinder. with a diameter of 8 and 4 single pieces high
