Answer:
The first one is -1/2
the second one is x+2y-27=0
Answer:
20.02%
Step-by-step explanation:
Formula : 
n = 1,2,3,4,5
Substitute the values in the formula :


Solving for IRR using calculator
IRR = 20.02
Hence the internal rate of return if the initial cost of the project is $275,000 is 20.02%
What factors to they have in common?
First, they're all even, so 2
if we divide all of them by 2, we get:
13,24,31
now, 13,31 are primes: so that means that those numbers don't have any more common factors!
So the greatest Common Factor of those 3 numbers is 2.
If you meant y = 27x - 3, OK. Then, if x = 4, y = 27(4) - 3, or 108-3 = 105.
Answer:
t ≥ 18
Step-by-step explanation:
He has run 12 miles plus some more miles t. He need to run at least 30 miles
12+t ≥ 30
Subtract 12 from each side
12+t-12 ≥ 30-12
t ≥ 18
