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

Step-by-step explanation:
remember that y=mx+b
So 2/5x would be you m.And -3/7 is your b
Hey there! I'm happy to help!
To find the area of a circle, you square the radius and then multiply by pi (3.14 in our case).
The radius is half of the diameter.
12.6/2=6.3
We square this.
6.3²=39.69
We multiply by 3.14
39.69×3.14=124.6266
We round to the nearest hundredth, giving us an area of 124.63 in².
Now you can find the area of a circle! Have a wonderful day! :D
Let the second no. be x
-3x = 21 → x = 21/-3 → x = -7
