Answer:
For chess club:
y1 = 16 + 1*x where y1=total number of members after x months
For film club
y2 = 4 + 4*x where y2=total number of members after x months
y1 = y2 at
16 + x = 4 + 4x
3x = 12
x = 4
Therefore, after 4 months they the same number of members (equals 20 members, 16 + 1*4 or 4 + 4*4).
If the answer is an equation then it is:
x=(4y+15)/(5-3y)
Answer:
176 girls
Step-by-step explanation:
31+44 = 75
300/75 = 4
4*44 = 176
176 girls in the school
1. 40/60 + 15/60 + 24/60 + 10/60 = 1.48
2.30/60 + 20/60 + 15/60 + 12/60 + 10/60 = 1.45
