Answer:
90
Step-by-step explanation:
3b/3=180/3
then u simplify
ur answer will be
b=90
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
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
