Noah scored 20 points in a game maya score was 30 points the mean score for noah maya and claire was 40 points what was claire score explain or show your reasoning

70 points

Step-by-step explanation:

Let n represent Noah's score, m as Maya's score, and c as Claire's score.

n=20

m=30

c=?

Let's try make an equation for this problem. The mean score for the three of them is 40, so the following equation is possible:

n+m+c/3=40

Now replace the variable with their values and continue to simplify.

20+30+c/3=40

Multiply both sides by 3.

20+30+c=120

Add 20 and 30 together.

50+c=120

Subtract 50 from 120 to find c.

c=70

Claire's score is 70 points.
