Answer:
It should be -3.75 because of how close .75 is rounding up to the next number which is -4
Where is the rest you cut it off
Find the common denominator. (12)
2•4=8
_ _
3•4=12
8/12•5/12=5/18
5/18 is your answer.
Hoped I helped!
Answer:
I think the answer would therefore be F.
we know
distance =time *speed
from given question we have following equation
4*t+(1.5-t)*8=10
4*t+12-8t=10
12-4t=10
-4t=10-12
4*t=2
t=0.5 hour
hence at speed 4 miles per hour he crosses 4*0.5=2 miles
at speed 8 miles per hour he crosses 8*(1.5-0.5)=8 miles
