The answer is 12x^3-4×^2-4
The easiest way to do this would be to imagine that Jolie has 100 marbles. If Mary has 40% fewer, that means she has 60 marbles. Then if they combine all their marbles into a single bag, they will have 160 marbles, of which 100 are Jolie's. So the % that is Jolie's is 100/160 = 0.625 = 62.5%.

Negative temperatures are basically the same as normal ones, although they go below zero, so they are still the same distance apart from zero, just on the left side of the number line.
To find the answer find the difference between 30.5°C and 0 (which is 30.5).
Next, find the difference between -122.2°C and zero (122.2)
Finally, add 122.2 + 30.5 to find the total distances from the zero combined for the full distances apart from each other.
(We add them because -122.2 to the left of zero, and 30.5 is on the right)
You should get 152.7 as your answer.

I'm guessing since it is asking for the deepest point (-5315) from sea level (0), the answer is -5,315 feet
*Remember 5,315 is negative because numbers below sea level are all negative*
So the answer should be -5,315 feet deep. (I'm not sure how to show your work for that I'm guessing it is 0 - 5,315 at the slightest).
*Hope this all helped :)*
The answer is 4x + 50.
Step by Step: -25+75= 50
