Hoang has worked as a nurse at Springfield General Hospital for 7 years longer than her friend Bill. Two years ago, she had been at the hospital for twice as long. How long has each been at the hospital

Hoang has been working for 16 years in the hospital, while Bill has been working there for 9 years.

Step-by-step explanation:

Since Hoang has worked as a nurse at Springfield General Hospital for 7 years longer than her friend Bill, and two years ago, she had been at the hospital for twice as long, to determine how long has each been at the hospital must be performed the following mathematical logical reasoning:

-The difference between the two is 7 years

-2 years ago, the difference was the same, but Hoang doubled Bill in the number of years, that is, she had been 14 years in the hospital, and Bill had been 7 yeats in the hospital (2 x 7 = 14).

-So, as of today, Hoang has been working for 16 years in the hospital, while Bill has been working there for 9 years.

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 : )

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
