Question

Markia had some cookies. She gave four to her sister. Then, she divided the remainder into two halves, and she still had five cookies left.

Answer 1

Answer:

Markia had 14 cookies.

Step-by-step explanation:

Let's represent the total amount of cookies as y.

We know that after she gave away 4 cookies and divided the remainder by 2, she had 5 cookies left.

This can represented as an equation.

$\frac{y - 4}{2}$ = 5

To solve this equation we have to isolate the y.

$\frac{y - 4}{2}$ = 5

Multiply both sides by 2 to isolate the y - 4:  y - 4 = 10

Add 4 to both sides to isolate the y:  y = 14

The total amount of cookies is 14.

Answer 2

Answer:

14

Step-by-step explanation:

x-4= no. of cookies that she had after giving 7 to her sister

$\frac{x-4}{2}$ after dividing the remaining half.

Times two to get rid of the denominator:

x-4=10

x=14

Markia had 14 cookies to start.
