Question

Question 10
If QR=16 and PR=95, find PQ.

Answer 1

PQ = 79

Explanation:

PQ + QR = PR

PR - QR = PQ

95 - 16 = 79

Answer 2

Okay, so the picture is a different question than the text.

The answer to the picture is:

67

The answer to the text is:

79

Explanation:

I'll explain the picture one.

The line PQR can be represented as
`PQ + QR=PR`. Since we already know the measure of QR and PR, we can substitute inside the equation to try and find PQ.

`PQ + 21 = 88`

Our goal is to isolate PQ on one side.

To do this we can subtract 21 from both sides.

`PQ + 21 - 21 = 88-21\\\\PQ=67`

Hope this helped!
