Answer:
Train A is faster by a factor of 1.01
Step-by-step explanation:
Given:
Train A:
Distance = 175 Miles
Time = 4 Hours
Train B:
y=43.5x
To Find:
which train travels at a faster rate in by what factor =?
Solution:
The speed of the train A =
The speed of train A =
The speed of train A = 43.75 miles per hour
Speed of the train B is the slope of the given line
The standard equation of the slope of the line is
y = mx+b
where m is the slope
and we are given with
y = 43.5x
So comparing with the standard equation
m = 43.5
Hence the speed of train B is 43.5 miles per hours
Train A travels faster
rate =1.01
Answer:
Given expression is,
9(x+3) = 108
In solving the equation the steps are as follows,
Step 1 : 9x + 27 = 108 ( By distributive property )
Step 2 : 9x = 81 ( Subtracting 108 on both sides )
Step 3 : x = 9 ( Divide both sides by 9)
Hence, by the above explanation we can drag the steps of solution in correct order.
