Working together, larry, moe, and curly can paint an elephant in 3 minutes. working alone it would take larry 10 minutes or moe 6 minutes. how long will it take for curly to paint the elephant alone

I'm only answering this one because I like the Three Stooges.

What's important in these questions is the rates, work per unit time, add up when we have multiple people.

Let c be Curly's rate in elephants per minute. Larry's rate is 1/10 elephants per minutes and Moe's is 1/6 elephants per minute. For the three of them to get done in three minutes means their collective rate is 1/3 elephants per minute:

Curly's rate is 1/15 th of an element per minute, so it would take him 15 minutes to paint an elephant.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
