A+b=13
a-b=7
add the two equations using system of equations
2a=20
a=10
10+b=13
b=3
The values are |-3.25| = 3.25 and |-4.25| = 4.25
<h3>How to determine the values of the expressions?</h3>
The expressions are given as
|-3.25| and |-4.25|
The above expressions are absolute value expressions
And as a general rule, an absolute value expression, when evaluated must follow the following rule
|±a| = a
Using the above as a guide, we have
|-3.25| = 3.25
Also, we have
|-4.25| = 4.25
Hence, the values of the expressions are |-3.25| = 3.25 and |-4.25| = 4.25

Let a = Imani's weekly allownace
She spent half of her allowance, so she has half it left = a/2. She got $4 more from washing the car, so she has a/2 + 4 dollars which totals $12:
a/2 + $4 = $12
a/2 = $8
Solve for a.
Can you explain.... Is there a question oooorrr no
