Answer:
x=8
x=-2
Step-by-step explanation:
∣x−3∣+4=9
= ∣x−3∣=5
<u>Positive term: (x-3)</u>
(x-3) = 5
Rearrange and Add up
x = 8
<u>Negative term: -(x-3)</u>
Multiply
-x+3 = 5
Rearrange and Add up
-x = 2
Multiply both sides by (-1)
x = -2
Yes she does have enough. Here is why:
If you add 1/4 and 1/4, you get 2/8 which is also 1/2.
3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4.
So she would have 1/4 left.
Absolutely enough to get to her friends house and back. :)
