Answer:
-18X^5
Step-by-step explanation:
(4 times 4 times 5) + (5 times 10 times 8) = 480 in cubed.
You're solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3Y' to each side of the equation.
7X + 3Y + -3Y = 0 + -3Y
Combine like terms:
3Y + -3Y = 0
7X + 0 = 0 + -3Y
7X = 0 + -3Y
Remove the zero:
7X = -3Y
<span>Divide each side by
'7'.
X = -0.4285714286Y
</span><span>Simplifying
X = -0.4285714286Y</span>
<span><span>A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?
----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

Solve for "x":
If amount of compound A is 4x = 255
