1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
Answer:
4/15
Step-by-step explanation:
because 1/5÷3/4=4/15
4.72n - 0.1 = 8 + 0.67n
4.72n - 0.67n = 8 + 0.1
4.05n = 8.1
4.05n/4.05 = 8.1/4.05
n = 2
Answer:
366 minutes
Step-by-step explanation:
divide 15000 by 41
32.
V = L*w*h
Where:
V= Volume
L= Length = x+5
w= width = x-2
h= height = 6
Replacing with the values given:
V= (x+5) * (x-2) * 6
V =[ (x*x) + (x*-2) + (5*X) +5*-2) ] * 6
V= [ x^2 - 2x + 5x - 10 ] * 6
V= [ x^2 + 3x - 10] *6
V= (x^2*6) + (3x*6)+ ( - 10 * 6)
V= 6x^2 + 18x - 60
