dinner?
2 answers:
$150
Answer: $150
Step-by-step explanation:
We can simplify 12.50 to 12.5, because the zero is behind the decimal point, and has nothing after it.
We multiply 12.5 (the cost of each portion) by 12 (the amount of portions) to get the total cost. If you are allowed to use a calculator you can just plug in the numbers, as so:
12.5 x 12 = 150
If not, and you need to show work, It'll look like the image I attached.
If you're unsure, you can use division to check your answer.

Answer:
x = 4 and x = 6
Step-by-step explanation:
There are two solutions to an absolute value equation.
If |x - 5| = 1, then
x - 5 = -1 and
x - 5 = +1.
1. Solve x - 5 = -1
Add 5 to each side.
x = 4
2. Solve x - 5 = 1
Add 5 to each side.
x = 6
The solutions are x = 4 and x = 6.
3. Number line
The number line would have markers at 4 and 6.
It should look like the image below.
