It takes nate four hours to paint a wall and it takes jill seven hours to paint the same wall about how many hours will it take
loris [4]

If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.


Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.


So, together, they paint the following fraction of the wall in one hour:


\frac{1}{4}+\frac{1}{7} = \frac{4+7}{28} = \frac{11}{28}.


At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint


\frac{11}{28}\frac{28}{11} = 1


i.e. the whole wall

Ms cais class is studying a study pattern.the rule for the tile pattern is y=10x-18.kalil thinks that figure 12 of this pattern
Allisa [31]

I assume that x = figure no.

It's better to write this as

Tiles = 10n-18

Thus 10(12) - 18

=120 - 18

= 102

THUS HE IS WRONG.
