-7x < 102
First step is to divide both sides by -7. Because we are dividing by a negative number, we have to flip the signs.
-7x < 102
x > -102/7
The only one of your answer choices that is greater than -102/7 is A. 20.
Hope this helped!
Garden one and two are both unknown, so I am choosing to call garden 2 X and then label garden 1 with comparisons to X.
It is tempting to list:
Garden Two = X
Garden One = X + 9
BUT there is an easier way. We are told that when 3 bushes are taken from garden 2 (x-3) and put in garden 1 (x + 12) then garden one has 1.5 times more than garden two.
Set it up like this:
1.5 ( x - 3) = x + 12 (because 1.5 times garden 2 will give us garden 1)
1.5x - 4.5 = x + 12 (Distribute)
.5x = 16.5 (Use subtraction to move variables to the right and other numb left)
x = 33 for Garden 2
33 + 9 for Garden 1 = 42

So it is just: 85 + 135 + 98 = 318 pages in total.
