I think it is 60 years old?
About 48 students are girls
Step - By - Step Explanation:
63 / 4 = 15.75
15.75 x 3 = 47.25
Because you can’t have 0.25 (1/4) of a person, you round to the next number.
Hope this helps!
Let us take 0instead of 2.2 meaning 8.5-2.2=6.3
then we need to find the mid of 6.3=3.15
then we need to add 2.2 to 3.15= 5.35
For graphing, the desmos graphing calculator is a big help :))
