Answer:
heres what i can find on the internet
Step-by-step explanation:
So, 5 walls = 4500 ft2 & since there are 5 people (all doing equal work) then each man paints 900 ft2 in 20 minutes. So, the total time is 20 minutes.
5x-3=2.5x+x solve this equation that I just gave you for X then plug it in to 2.5x and that will equal MN
Answer:
34
Step-by-step explanation:
180 since it is supplementary
then minus 100 which is 80 then minus 12 which is 68 then half that which is 34
Answer:
9.8
Step-by-step explanation:
Mn - 4m - 5n + 20
In this, mn and -4m have a common factor; m. So we can take that out to make it:
m(n-4) -5n + 20
Now, -5n + 20 also has a common factor which is 5, because 20/5 gives you 4, and 5/5 equals 1. So we can talk out that -5 (it doesn't need to be negative, but negatives on variable, no gusta). So you'd get
m(n-4)-5(n-4) OR m(n-4)+5(-n+4)
