Three art students used a total f 28 1/2 inches of string for an art project each student used 2 1/2 inches of string plus an additional 1 3/4 of string for each day rthey worked on the art project each student worked on the project the same number of days which equation could be used to find d the number of days the students worked on the art project

Step-by-step explanation:

Let the number of days that they worked on this art project be represented by x

We are told that:

Three art students used a total of 28 1/2 inches of string for an art project each student used 2 1/2 inches of string plus an additional 1 3/4 of string for each day rthey worked on the art project

For 1 student, let y represent the total number of inches of string used by each student

The Equation is given as:

2 1/2 + 1 3/4 x = y

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 : )

x = 12

y = 1

for the points!
