If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66
If he sold all 60 of the CD's for 5 for $12, he'd make $144.
Subtract the income by the original buying price to find his profit. $144 - $90
The peddler made $54 profit.
Answer:
Factoring a monomial means breaking it down into each individual prime number and/or variable factor. This is also called "expanding" a monomial.
Step-by-step explanation:
The answer would be D)12/4 because if 4 quarts=1 gallon then 12/4=3 gallons
That means that the first rectangle and the first triangle ave athe same perimiter
so therefor
perimiter=sides added up
rectangle has 4 sides bu 2 is given so double it since the other side is same legnth
rec=x+x+4
multiply 2
2x+2x+8=4x+8=perimiter
this is equal to perimiter of triangle which is
x+9+x+5+x=3x+14
therefor
4x+8=3x+14
subtract 3x from both sides
x+8=14
subtract 8 from both sides
x=6
first one x=6
second rectangle and second triangle
s+7 and 3s
2 sides
2s+14+6s=p
8s+14=p
traignel=2s+12+2s+12+2s+12=6s+36=p
they are equal so
8s+14=6s+36
subtract 6s from both sides
2s+14=36
subtract 14 from both sides
2s=22
divide both sideds by 2
s=11
the values are
pair one:
x=6
pair 2:
s=11
