Rachel bought a piece of fabric 2.3 meters long and a piece of fabric 3.45 meters long. she needs 10 meters of fabric altogether. how much more does she need to buy?
5. write and solve the arthmetic problem for each step.
add the length of one piece to the length of the other piece.

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

the answer should be a. snail

answer: the answer is d
