Step-by-step explanation:
5(r + 9) - 2(1 - r) = 1
5r + 45 - 2 + 2r = 1
7r + 43 = 1
7r = -42
r = -6.
Since 1/4 = 2/8, we know that there will be enough paint for a bookshelf because 4/8 + 2/8 = 6/8 (less than 7/8)
Let, the number = x
It would be: x * 0.32 = 16
x = 16 / 0.32
x = 50
In short, Your Answer would be 50
Hope this helps!
