What you have to do is multiply 21 by 2. it is 42. $42 dollars was the original price of the bookcase.
3^2 + 16
= (3 • 3) + 16
= 9 + 16
= 25

10÷1/2/3=?
10÷5/3=?
10×3/5=?
30/5=6
6 is the answer
I took 400 - 150 divided by 15 and got 16. So believe that should could afford to bring 16 people.
Answer:
12.5 or 12 1/2 Slices left
Step-by-step explanation:
30 divided by 6 or (1/6) is 5
So,
Violet ate 5
Sophie ate 5 (same amount)
30 divided by 5 or (1/5) is 7.5
so we add 5+5+7.5 = 17.5 and subtract it from 30 to get our left over slices which comes up to
12.5 or 12 and 1/2 slices
hope this helps
