Yes if they relate to one another using an = sign
Lst question: x = 5, y = 7
2nd question: x = -1, y = 5
3rd question: x = 98, y = 80
Absolute value equations have more than one solution because when the answer is in abs. value, it is positive, so there could be a negative answer and it would still be positive. For example |-5|=5 and |5|=5 as well.
4+|2x|=-1 would have no solution because you cannot have the equation equal a negative since the 2x is in absolute value.
Answer:
$11.20 per hat.
and $5.60 per bag
Keisha has $13.20 left over
Step-by-step explanation:
First, I multiplied .70 by 16 and got 11.20 per hat
Then, I multiplied .35 by 16 and got 5.60 per bag
Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from 30 and got 13.20.....
