The first question would be x + (x + 4). This is because Max has $x and Keisha has (x + 4) because she has four MORE THAN Max. I am pretty sure that the second one is A, but I am not positive. The first one is right though. I hope this helps!!!

Answer:
o.o326
Step-by-step explanation:
when dealing with negative exponents you move the decimal to the left
First step: combine the x terms, x - 4x = -3x.
Second step: Add 32 to both sides, which will cancel out the -32.
Now you have -3x = 32.
To solve for x, divide 32 by -3. The answer is -10.667.
Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
