Steps

4² x +3=1

4²=16

16x + 3=1

Subract 3 from borh sides

16x +3-3=1-3

Simplify

If there are 35 yellow books in the bookcase, then how many green books are in the bookcase
alukav5142 [94]

ANSWER

D. 14

EXPLANATION

The ratio of the books in the book case are:

Red:Yellow:Green=3:5:2

The number of yellow books in the book case is 35.

If 5 corresponds to 35, then 2 green books will correspond to a less number of books,

By proportion, because it is going to be less more will divide.

The number of green books in the book case is

=  \frac{35 \times 2}{5}

= 7 \times 2 = 14
