Over 5 weeks 20 reduction in waste removed.
Therefore 4 per week.

Therefore gradient -4w.
-4 x 5 + c = 60
-20 + c = 60
c = 80

dumpsters removed = d
weeks = w
d = 80 - 4w

7(5x + 9) = 12 - (x +9)

den301095 [7]

Answer:

$\frac{-5}{3}$ is the answer

Step-by-step explanation:

7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)

7(5x+9)=12+−x+−9

(7)(5x)+(7)(9)=12+−x+−9(Distribute)

35x+63=12+−x+−9

35x+63=(−x)+(12+−9)(Combine Like Terms)

35x+63=−x+3

Add x to both sides.

35x+63+x=−x+3+x

36x+63=3

subtract 63 from both sides.

36x+63−63=3−63

36x=−60

Divide both sides by 36.

$\frac{36x}{36} =\frac{-60}{36}\\$

-5/3 is the answer.
