Answer:
7 points
Step-by-step explanation:
Let n represent the points Rayanna score.
We can use this to set up an equation:
11=3n-10
Add 10 to both sides:
21=3n
Divide both sides by 3
n=7
Therefore Rayanna scored 7 points
Solution:
Note that:
- L = 3r - 10
- L = 11
Substitute the value of L into the equation to find r.
- L = 3r - 10
- => 11 + 10 = 3r
- => 21 = 3r
- => r = 7
Rayanna scored 7 points.
