11. Rihanna works in a coffee shop approximately eighteen miles from her apartment. She bikes
every day from her apartment to the coffee shop and then back to her apartment in the
evening. On her way to work, she always stops halfway through to meet her best friend at a
park. If the distance from Rihanna's apartment to the park is (2x + 5) miles and the trip form the
park to the coffee shop is (25 – 8x) miles long, then what is the value of x?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
