Step-by-step explanation:
Car A a) 300/37 + 100/30 = 11.441441441... 11.4 gal
b) 100/37 + 300/30 = 12.702702702... 12.7 gal
Car B a) 300/27 + 100/37 = 13.813813813... 13.8 gal
b) 100/27 + 300/37 = 11.811811811... 11.8 gal
Answer:
8
Step-by-step explanation:
Answer:
l=15
Step-by-step explanation:
let length=l
width=w
l=3w-2
w=(l+2)/3
Perimeter P=2(l+w)=2[l+(l+2)/3]=2(4l+2)/3≤43
2(4l+2)≤129
8l+4≤129
8l≤125
l≤125/8
so l=15
________________
P=2(l+w)=2(3w-2+w)=8w-4≤43
8w≤47
w≤47/8
l≤141/8-2
l≤125/8
l=15
