Answer:

<em>x</em> = 45 points

Round 3 : 45 points

Step-by-step explanation:

<u>Starting Information:</u>

100 points = 3 rounds

Round 1 : 30 points

Round 2 : 25 points

Round 3 : <em>x</em>

<u>Subtraction:</u>

To find <em>x </em>we need to subtract 30 and 25 from 100

100 - 25 - 30 = <em>x</em> points

<em>Combine -30 and -25 into -55</em>

100 - 55 = <em>x</em>

100 - 55 = 45

In round 3 he scored 45 points

<u>Addition:</u>

To find <em>x</em> we need to add 30 + 25 + <em>x </em>and get a sum of 100

25 + 30 + <em>x </em> = 100

<em>Combine 25 and 30</em>

55 + <em>x</em> = 100

<em>Subtract 55 from each side</em>

<em>x </em>= 45

Here are the 2 expressions I used:

25 + 30 + <em>x</em> = 100

100 - 25 - 30 = <em>x</em>

Note:

My work is not number assigned but hopefully you can understand it :)
