Answer:
<em>Ethan is 31 years old.</em>
Step-by-step explanation:
If Alex is 7 years younger than Ethan, then Ethan is 7 year older than Alex.
Alex is 24 years old, so Ethan is 24 + 7 years old.
24 + 7 = 31
Ethan is 31 years old.
I would solve this by using elimination, because you have opposite coefficients, (7x and -7x)<span />
No, the absolute value is the distance from zero, positives and negatives don't count in absolute values, it's all about the distance.
Example: |-6| > |4|
14/32 is left because you subtract 32 by what was eaten and out your answer over what was there before some of it got eaten.
