Jena and matt, working together, can mow the lawn in 4 hours. working alone, matt takes four times as long as jena. how long does it take jena to mow the lawn alone?

For this case, the first thing we must do is define a variable.

We have then:

x: number of hours that jena has to mow the lawn alone.

We now write the equation that models the problem.

We have then:

From here, we clear the value of x.

We have then:

it takes jena 5 hours to mow the lawn alone

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 : )

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
