Two students, Raymond and Shauna, are trying to get city council members to vote for a new park along the river. 2/6 of the 24 c
galina1969 [7]
Raymond and Shauna must convince at least 5 more city council member. Because if every 2/6 members agree with the idea, then there would be 8 people out 24 that already agree with the idea. So if you have already 8 members then to make 13, you just need 5 (8 + 5=13) more people to 13.

Katie is twice as old as her sister Mara. The sum of their ages is 24. Find their ages.
Alenkasestr [34]
So k=katie's' age
m=mara's age

k is 2 times as old as m
k=2m

sum is 24
add means sum
k+m=24

so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16

katie=16
mara=8

A girl is 18 years old and her brother is a third of her age. When the girl is 36 what would be the age of the brother?
ale4655 [162]
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old

Now when she gains another 18 years (36-18=18) he will also gain those 18 years

When she is 36 he will have 6+18=24 years old

Answer is 24.
