<h3>
Answer:</h3>
<em>Your answer would be y=x+3/12</em>
<h3>
Step-by-step explanation:</h3>
Firstly, you'll switch sides of the equation.
<em>y=12x+3 ---> x=12y-3</em>
Next, add 3 to both sides.
<em>x=12y-3 ---> 12y-3+3=x+3</em>
Simplify it.
<em>12y-3+3=x+3 ---> 12y=x+3</em>
Then, divide both sides by 12.
<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>
Simplify once more.
12y/12 = x/12 + 3/12 --- y= x+3/12
<u>y=x+3/12 would be your answer.</u>
Answer: y = $500 + (25%)x
Y = $500 plus 25% times x
Step-by-step explanation:
The volume of a cube with side length equal to x, is

,
thus, the volume of a cube shaped box, whose side length is (5a+4b) is :

,
The volume is already expressed in terms of a and b, but we can expand the expression

, as follows:
![(5a+4b)^{3} =(5a+4b)(5a+4b)^{2}= (5a+4b)[ (5a)^{2}+2(5a)(4b)+ (4b)^{2}]](https://tex.z-dn.net/?f=%285a%2B4b%29%5E%7B3%7D%20%3D%285a%2B4b%29%285a%2B4b%29%5E%7B2%7D%3D%20%285a%2B4b%29%5B%20%285a%29%5E%7B2%7D%2B2%285a%29%284b%29%2B%20%284b%29%5E%7B2%7D%5D)

20x20=400
pi(3.14) x 10^2(100)
100x3.14=314
400-100pi=85.8407 (then you can round if you need to)
