Answer:
$0.5
Step-by-step explanation:
Given data
Cost of 5 pencils= $2.50
Required
The cost per pencil
The cost per pencil is
Cost of 5 pencils divided by 5
=2.5/5
=$0.5
This is the constant of proportionality
For any number of pencils x
The cost is
Cost =0.5x
Hence the cost of one pencil is $0.5
Jamie's claim isn't reasonable. This is because half of 4/5 is 4/10 and if you simplify it, it is 2/5.
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
Answer:
Look at the pics
Step-by-step explanation:
Hey, so when I was solving this I accidentally numbered the exercises differently than in your pic....
I just went from the left row to the right (and missed two...)
Hope it doesn't confuse you :]
If you have any questions about the way I solved it, don't hesitate to ask me =)
