Answer:
r = -3
Step-by-step explanation:
- 60= - 24 + 12r
Add 24 to each side
- 60+24= - 24+24 + 12r
-36 = 12r
Divide each side by 12
-36/12 = 12r/12
-3 =r

Answer:
The nursery has a fixed rate and another variable.
The fixed is a total of 3 dollars. The variable changes depending on the delay time when picking up a child.
In this case the child is Albin, who presents the following equation:
10.50 = 0.50 * a + 3
Therefore, it would be the minutes for late pickup of Albin.
-12 = f/0.2
First, we can start out by making our goal to get the variable (f) on one side of the problem by itself. To do this, multiply both sides by 0.2.

Second, our next step is to multiply -12 times 0.2. This can be solved in your head, on a piece of paper, on a calculator, etc. (-12 times 0.2 = 2.4).

Third, our last step will be to switch sides. Basically flip the problem.
