Rosa and Leann are working on a group English assignment. They each write one
essay alone and then one essay together. Leann takes 6 hours longer than Rosa to
write her individual essay. Writing at the same rate, they complete their combined essay
in 4 hours. How long does it take Leann to write her individual essay?
hours

10 hours

Step-by-step explanation:

It said Leann takes 6 hours longer than than Rosa to write her individual essay

4+6=10 hours

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
