On math!

beth's monthly charge for internet access c is represented by the function c = 12 + 2.50h, where h represents the number of hour of usage during a month. what is the total charge for a month in which beth used the internet for 9 hours?

a. $39.95
b. $34.50
c. $27.00
d. $22.50

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
