Answer:
1.68 pints
Step-by-step explanation:
First you need to determine how much blue paint she used, then you can determine how much white paint she used. :)
4/5 of 8.4:
4/5 * 8.4 = 6.72 pints
Now we can determine how many pints of white paint she used by subtracting 6.72 from 8.4:
8.4 - 6.72 = 1.68
So she used 1.68 pints of white paint. :) Hope this helped!

Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
