a negative times a negative is a positive answer so both 5 *6 and -5 *-6 = 30
the answer is C
Hope this helps have a nice day:)
Answer:
9
Step-by-step explanation:
Set it up as the following -
3:8 = x:24.
Now cross multiply - 3 * 24 = 8x
72 = 8x
Now divide both sides by 8.
9 = x
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 .
