Naomi and Claire are painting a mural. Naomi paints 2 square feet per hour and has already painted 16.5 square feet. Claire paints 4 square feet per hour and has already painted 7.5 square feet. How many more hours will it take for Naomi and Claire to paint an equal total number of square feet? Enter your answer in the box. hours Show equation next to answer please.​

step-by-step explanation:

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

thats not a system of equations, that is a solution
