2(6 − 2x) + 3x = 4 + 2(5 + x) what is x

alexira [117]

First let's get rid of the parenthesis:

12 - 4x + 3x = 4 + 10 + 2x

Now group the x's on the left and the numbers on the right

-4x + 3x - 2x = 4 + 10 - 12

...and simplify

-3x = 2

divide by -3 to isolate x

x = -2/3

What’s the equation to convert 100 inches per minute to feet per hour

laiz [17]

Let's look at each part of the equation. We need to first convert the inches to feet then multiply it by 60 to get per hour.
To convert inches to feet, we need to divide by 12.
100÷12
8 1/3
We need to then multiply it by 60 to find per hour.
8 1/3×60= 500
Let's put the equation together, we'll need parenthesis.
$( \frac{100}{12} )*60=500$
