Josette found 16 coins in her purse. She had 2 more nickels than pennies and 7 fewer quarters than pennies. Josette modeled the scenario in a table and then wrote the equation p + (p + 2) + (7 – p) = 16. A 2-column table with 3 rows. Column 1 has entries pennies, nickels, quarters. Column 2 has entries p, p + 2, blank.

Is Josette’s equation correct? If not, what was her mistake.
Her equation is correct.
The variable should have been the number of nickels.
Instead of finding the sum, she needed to write an equation to find the
difference.
The number of quarters was translated incorrectly and should be p – 7.

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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 : )
