Answer:
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.
Step-by-step explanation:
The scale he uses is
15 ft= 3 cm
1 feet = 3/15 cm
1 cm= 15ft/3= 5 ft
One lane = 60 ft long and 5 ft wide
In centimeters it would be 60 ft / 5ft = 12 cm long and 5 ft/5ft= 1 cm wide
The width of 1 lane is 1 cm .
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.

Answer: The value of x is -5 and the value of y is 5.
Explanation:
The slope of the line is
and the point is (-2,5) from which the line line is passing.
If a line is passing through the point
with slope m, the the equation of line is,



..... (1)
It is given that the point A(x,3) and B(-2,y) lies on the line. It means it satisfies the equation of the line.
Put y=3 in equation (1).


The value of x is -5.
Put x=-2.




The value of y is 5.
