Distribute the 15 through the parentheses, like so-
30b+45
Multiply both sides by b to get a = bc.
You multiply .2 by every number in the parentheses. So .2 times 2.50, which is 0.5, .2 times 4.95, which is .99 and .2 times by 6, which is 1.2. then you add .5, .99 and 1.2 to get 2.69.
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.
Step 2: Divide both sides by 2.
3. (Solving for 2nd condition)
Step 1: Add 1 to both sides.
Step 2: Divide both sides by 2.
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:
