Answer:
age
Step-by-step explanation:
Width=x-6
lenght=x
Perimeter of a parallelogram=2(lenght)+2(width)
Data:
Perimeter=60 m
Therefore:
2(x)+2(x-6)=60
2x+2x-12=60
4x=60+12
4x=72
x=72/4
x=18
Width=x-6=18-6=12
Lenght=x=18
Answer: the lenght would be 18 m, and the width 12 m
I have 2 brothers and 2 sisters. My mother said if we were good, we would get our allowance. The 5 of us were playing catch in the house. When I tried to catch the ball, I accidentally knocked over my mom's decorative vase and it broke. Needless to say that we did not get our allowance. It cost $50 to replace the vase. My brothers and sisters agreed to share the cost. How much did each person earn?
It's kind of silly, but that's all I can think of.

Imagine for a group of 15 (8 boys and 7 girls), you will have 8 girls. So the ratio of girls to total campers is 8/15
Because we have 195 campers, we have 8/15 = x/195
solve for x
x= 104 girls
and we have 195 - 104 = 90 boys
