Find the LCM between the denominators.
The LCM is 36
Divide he LCM for the denominators, then multiply the result for the numerator.
You get 25/36 and you can't simplify it
Answer:
F(0)=0
Step-by-step explanation:
Because if you substitute 0 for x
F(x)=3x+5
Then calculate the product
F(0)=3(0)+5
Now remove 0 from the equation
F(0)=0
And there's your answer!! Hope this helped!!
Answer:
f(x)=0.17x+3.00
f(60)=0.17(60)+3.00
f(60)=10.20+3
f(60)=13.20
1 hour will cost $13.20
Step-by-step explanation:
I found the difference in minutes between the given values and the difference in cost between the given values. Between 8 minutes and 25 minutes is 17, and between 25 and 40 is 15 minutes. The difference of $7.25 and $4.36 is $2.89, and the difference between $7.25 and $9.80 is $2.55. I then divided2.89 by 17 and 2.55 by 15 and both resulted in $0.17/minute. I them multiplied 8 minutes by $0.17 toget $1.36. I subtracted that from the cost given for 8 minutes to get $3.00. The $3.00 is the initial charge, or b in slope-intercept form with m=0.17. Plug in 60 for x to find the cost of an hour.
Answer:
The first one (Cedric is correct because he used the inverse of subtraction and added 4.5)
Step-by-step explanation:
First....I'll do it my way
z - 4.5 = -1.5
Add 4.5 on both sides
z - 4.5 + 4.5 = -1.5 + 4.5
z = 3
This should be our answer.....and so who did it right?
Cedric did
Which is the true statement?
Cedric is correct because he used the inverse of subtraction and added 4.5
Hope this helped!
