ABSOLUTEEE VALUEEEE HELPP PLZ

Answer:

Last option; x < 2 and x > -1

Step-by-step explanation:

1. We know 2x − 1 < 3 and 2x − 1 > −3, so let's solve both of these inequalities.

2. (Solving for 1st condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 < 3 + 1$
$2x < 4$

Step 2: Divide both sides by 2.

$\frac{2x}{2} < \frac{4}{2}$
$x < 2$

3. (Solving for 2nd condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 > -3 + 1$
$2x > -2$

Step 2: Divide both sides by 2.

$\frac{2x}{2} > \frac{-2}{2}$
$x > -1$

4. Now, we know that the value of x is greater than -1 but less than 2, and we can represent it on a number line like this:

You have 12 balloons to blow up for a party. You blow up 1313 of them, and your friend blows up 5 of them. What fraction of the

photoshop1234 [79]

12 balloons total
u blow up 1/3.....1/3(12) = 12/3 = 4....so u blow up 4 out of 12...thats 4/12
ur friend blows up 5...he blows up 5 out of 12....thats 5/12

so 4/12 + 5/12 = 9/12....9/12 are blown up.....that leaves 3/12 or 1/4 left to blow up
