Answer:
2 
pizzas
Step-by-step explanation:
The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.
To multiply 5/6 by 3, we can set it up as 
. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as . In total, they ate 2 pizzas.
Hope this helps!
First lets write out the equation:
-8x + 2x - 16 < -5x + 7x
Lets collect the x values
-6x - 16 < 2x
-8x - 16 < 0 (subtract both sides by 2x to get all the x's on one side)
-8x < 16 ( add both sides by 16 to get all the x's alone)
x < -2 ( divide both sides by -8 to get what just x is)
So x < -2
