Edward made 4 stacks of wooden blocks. The first stack was 9 blocks tall. The second stack was 9 blocks taller than the first. The third stack was 4 blocks shorter than the second stack, and the last stack was 4 blocks taller than the third stack. How many blocks did Edward use in all? Y’all I need help ASAP was due yesterday and need to turn in RN ik it might be easy but I am just

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

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
