So first you would put these over a common denominator which is 96. You get this by multiplying by 9 and what you do to the denominator you must do to the numerator so you then get 45/96 and 63/96. Pelicans=45/96. Woodpeckers=63/96
You said that n = 5m
AND n = m + 36 .
Well then, if those two quantities are both equal to 'n', then
they must be equal to each other, and we can write
5m = m + 36
Subtract 'm' from each side: 4m = 36
Divide each side by 4 : m = 9 .
OK. We're half done.
Way back at the beginning, the first thing you told me
was that 'n' is 5 times the value of 'm'.
n = 5 (m)
Well ! Now we know what 'm' is, so
n = 5 (9) = 45 .
Answer:
what's the formula that you're supposed to apply the x to ?
Answer:
7.5 days.
Step-by-step explanation:
Let t represent time taken by Nick in days to paint the house alone.
Part of house painted by Nick in 1 day would be 
.
We have been given that Brad paints a house in 5 days, so part of house painted by Brad in 1 day would be 
.
We are also told that when Brad's brother Nick joins him, they can paint a house in 3 days. So part of house painted by both Brad and Nick together in 1 day would be 
.
Now, we will equate sum of work done by both brothers with to solve for t as:
Therefore, it will take 7.5 days for the Nick to paint the house alone.
An absolute value cannot equal a negative number. So c, if it was a negative number, would have no solution.
