There are 16 mystery books 22 history books and 21 science books in a large bookcase. a smaller bookcase has 30 fewer books. how many books are in the smaller bookcase

You have 29 on the smaller case

Step-by-step explanation:

if you add all the numbers (16, 22, 21) you will get 59

but its asking for the smaller case

so if you take the 59 and subtract 30 from it you get 29

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
