Step-by-step explanation:
there's 42 liters of juice right? so to <u>divide</u> it into six batches all you got to do is divide all the liters of juice into how many batches you need. So as it says in the question, just divide 42 by 6 and you'll get your answer which is 7.
Answer:
- 1/2
Step-by-step explanation:
62=2w+2l
120= 2(2w)+ 2(l+21)
120=4w+2l+42
78= 4w+2l
39=2w+l
39-2w=l
Use substitution
62=2w+2(39-2w)
62= 2w+78-4w
62= -2w+78
-16=-2w
8=w
Plug w in
62=2(8)+2l
62=16+2l
46=2l
23=l
Final answer: Width=8, Length=23
