sarah and rachel each have apps on their phones. the number of apps on sarahs phone can be represented by x. the number of apps on rachels phone is 4 more times the number of apps on sarahs phone. the total number of apps on both girl's phones is 115. what is x the number of apps on sarahs phone?

Let's represent the number of apps on Sarah's phone as x.

Therefore, the number of apps on Rachel's phone is 4 + (4 * x).

The total number of apps on both girls' phones is x + (4 + 4x) = 115.

Combining like terms, we get 5x + 4 = 115.

Subtracting 4 from both sides, we get 5x = 111.

Dividing both sides by 5, we get x = 22.

Therefore, the number of apps on Sarah's phone is 22.

72 divided by 5

The quotient of 72 divided by 5 is 14 remainder 2.

115 divided by 4

The quotient of 115 divided by 4 is 28 remainder 3.

To solve this problem, we will set up an equation based on the given information.

Let's start by representing the number of apps on Sarah's phone as x.

According to the problem, the number of apps on Rachel's phone is 4 more times the number of apps on Sarah's phone, which can be written as 4x.

The total number of apps on both girls' phones is 115, so we can write the equation:

x + 4x = 115

Now, we can simplify the equation by combining like terms:

5x = 115

To solve for x, divide both sides of the equation by 5:

5x/5 = 115/5

x = 23

So, the number of apps on Sarah's phone, represented by x, is 23.
