Is this a joke because it made me laugh
First, multiply both sides by 1000
1000*c = w*t*c
Since c is on both sides, they would cancel each other out
1000 = w*t
Divide both sides by t.
w = 1000*t
<span>Well, they couldnt have studied negative time.. So Id say the domain is \(x \ge 0\) where \(x\) is the time they studied.</span>
Factors are the numbers you multiply together to get another number. When you find the factors of two or more numbers, and then find some factors are the same ("common"), then they are the "common factors<span>"
</span>Example: 12 and 30
• The factors of 12 are: 1, 2, 3, 4, 6 and 12
• The factors of 30 are: 1, 2, 3, 5, 6, 10, 15 and 30
<span>So the common factors of 12 and 30 are: 1, 2, 3 and 6

-Hope this helped.
