Answer:
x=33
Step-by-step explanation:
Let x = # of coffee mugs sold
x * 3.50 = 115.50
Divide by 3.50 => x=33
0 = 3x² + 2x - 2
Perfect example of a leading coefficient (coefficient of the highest degree term) of 3 and a constant term (degree zero) of -2. CHECK ME
0 = -2 - 3x² + 3
That has a leading coefficient of -3 and a constant of -2+3=1, so don't check me.
0 = -3x + 3x² - 2
CHECK ME. The order we write the terms doesn't matter; the leading coefficient is on the highest degree, 3x² here. The constant is -2.
0 = 3x² + x + 2
The leading coefficient is indeed 3 but the constant is a positive two, don't check me.
0 = -1x - 2 + 3x²
CHECK ME. Again, the written order of the terms doesn't matter; it's the degree that matters.
Kilometers per hour and miles per hour would be the most reasonable to measure someone running a race. Millimeters and inches are too small.

Step-by-step explanation:
Step 1:
(3x + 12y) + (10x - 5y)
<em>{Distributive property A(B+C)=AB+AC}</em>
-------------------
Step 2:
(3x + 12y) + (-5y + 10x)
<em>{Commutative property A+B = B+A}</em>
-------------------
Step 3:
3x + (12y - 5y) + 10x
<em>{Associative property A+(B+C)=(A+B)+C}</em>
-------------------
Step 4:
3x + 10x + (12y - 5y)
<em>{Commutative property A+B = B+A}</em>
-------------------
Step 5:
13x + 7y
<em>{Simplification}</em>
