What is the answer to -3+p=?
nata0808 [166]
There is not an answer to an expression. 

-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x. 

-3+p simply equals -3+p

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?
Anestetic [448]

Answer:

Rudy is 13 years old. Her father is 45 years old.

Step-by-step explanation:

It's very simple actually!

<u>All you need to do is subtract 32:</u>

58 - 32 = 26

<u>Then divide:</u>

<u />

26 ÷ 2 = 13

13 is Rudy's age. Let's find her father's age!

<u>We then add 32 back to 13:</u>

32 + 13 = 45

And there you have it!

Hope this helped!  :)
