Answer:
Step-by-step explanation:M+F=39
M+F=39
F=M-9
Substitute
M + M - 9 = 39
2M = 48
M=48/2
M=24
24+F=39
F=39-24=15
F=15, M=24
Answer:
a common factor would be 5m^4n^3 or 15m^2n^2
Step-by-step explanation:
not sure what terms they want you to choose from but anything that starts with a number (5,10,15,) and "m" would any number 5 would go into
Answer:
x=2(m+n+1)
Step-by-step explanation:
I am assuming you mean: (X-2)/2 =m+n
X-2 =2(m+n)
X =2m+2n+2
x=2(m+n+1)
Answer:
12-3+(2.7x2)-7
Step-by-step explanation:
you would have to divide each number in the equation by 3 which would look like this:
36 / 3 = 12
-9 / 3 = -3
8 / 3 = 2.6666 repeating, which would be rounded up to 2.7
6 / 3 = 2
-21 / 3 = -7
i hope this helps :)
