1/9 • 5/4 = 1/9 • 1 1/4 = 11/36. Hoped I helped!
Factoring yields: (x-5)(x-8) = 0
x-5 = 0 x = 5
x-8 = 0 x = 8
Answer:
If you buy a diaper online instead of Babies-R-us, you save 4 cents more.
Step-by-step explanation:
If 56 diapers cost 28
then 1 diaper cost x
56x = 28
x = 28/56
x = 0.5 or 50 cents
If 112 diapers cost 52
then 1 diaper cost x
112x = 52
x = 52/112
x = approximately 46 cents.
