Answer:
19 of 24
Step-by-step explanation:
in this case each question is 1 point, or a substitute variable, <em>a.</em>
He used 12 gallons of white paint.
Because 20 divided by 5 = 4. Meaning that 4 gallons is one part.
4 x 5 = 20
4 x 3 = 12
2x - 9x = 14 (Careful next time you accidentally added an "equal" next to the 2)
-------------------------------------
Simplify
2x-9x=<span>14
</span><span>2x+-9x</span>=<span>14
</span>--------------------------------------------
Combine the like-terms
<span>(<span>2x+-9x</span>)</span>=<span>14
</span><span><span>-7x</span></span>=<span>14
</span>--------------------------------------------------
Now divide -7 to each side
-7x ÷ -7 = 14 ÷ -7
x = -2
------------------------------------------------------
x = -2 is your answer
