First, let's list the factors of each number
150: 1, 150, 2, 75, 3, 50, 5, 30, 6, 25, 10, 15
135: 1, 135, 3, 45, 5, 27, 9, 15
From these lists, we can say for certain that 1, 3, 5, and 15 go into both numbers, so that would be your list of the common factors.
I hope this helps!
This one is easy. All you have to do is divide 84/7. and then you will have the amount of 12 so each of Danny's friends contributes $12.
I think it would be:
10, 12.5, 17, 19.5, 23
hope it helps
We do
how much added-howmuch subtracted

-

or

so
first simlify F(t)-E(t) (if you want, not necicary if use calculator)
(t+7-ln(t+4))/(t+2)=F(t)-E(t)
evaluate

≈9.05584
about 9 pints
It’s positive!! hope that helps!
