Tammy's dad worked 618 hours in half a year. louie's mom worked 487 hours in half a year.

( i have to write a comparison sentence for the problem.)

Tammy's dad works 131 hours more compared to Louie's mom out of a possible 4380 hours.

Step-by-step explanation:

A half years is:

182.5 days and we can convert to hours by multiply by 24 hours per day:

4380 hours in a half year:

Tammy's dad works 618 hours of 4380 hours and Louie's mom works 487 hours of 4380 hours.

Comparison sentence:

Tammy's dad works 131 hours more compared to Louie's mom out of a possible 4380 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
