Answer:
Therefore 160 workers needed to build 16 miles of highway in 15 weeks.
Step-by-step explanation:
Given that,
the amount of time to build a highway varies inversely with the number of workers and varies directly with the length of the highway.
i.e
T= time, L= length of highway and W= number of workers.
So,we can rewrite the above equation
Here, = 100 worker, = 4 miles, = 15 weeks
= ?, = 16 miles, = 15 weeks
[ Multiply both sides]
Therefore to build 16 miles of highway in 15 weeks 160 workers needed.
Answer:
length=14 width=5
Step-by-step explanation:
since the length is 4 more then subtract 4*2=8 which would equal 30 divide that by two since a rectangle has 4 sides two of which are the same,
than divide it by the getting 5 which is the width.
subtract 5*2=10 from 38 which would = 28
28divided by 2 is the length which is 14
Y = 4x is not a linear equation.
