Answer:
x = 1/2
Step-by-step explanation:
(x + 2)2 + (9 - 3)2 = 4
2x + 4 + 18 - 6 = 4
2x + 16 = 4
2x = 4/16
2x = 1/4
x = 1/4/2
x = 2/4
x = 1/2
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
