Answer:
There are more than one way to do this:
Here's one way:
The least common multiple of 4 people and 3 people is 12 people.
12 people is 3 times as many people as 4 people, and
12 people is 4 times as many as 3 people.
Since 4 people take 6 days, 3 times as many people take only
one-third as long, or only 2 days. (since 2 is one-third of 6)
Since 3 people is only one-fourth as many people as 12, it will take
them 4 times as long as it would take 12 people, or 8 days. (since
4 times 2 is 8).
Step-by-step explanation:
subtract 8 from 12
4 days
When dividing these, the powers are subtracted form each other.
We could split up the fraction into r's, s's, and t's.
r^-3 / r^2 = r^-5 [think of it as -3 -2]
s^5 / s = s^4
t^2 / t^-2 = t^4 [2 - - 2 = 4]
A negative power places it on the bottom of the fraction and the minus sign is removed from the power.
So the answer is A: (s^4)(t^4)/r^5
I assume you're looking for the sum.
I would use the null property to eliminate 0
34+0+18+26
=34+18+26
then use commutativity to rearrange
=34+26 + 18
Add 34+26=60
=60+18
=78
