2x-y-1=0
There are 2 ways that you can solve this . Either plug in the x and y value into each equation until it is right or rewrite the equation .
the equation in slope intercept form is y=2x-1
When you get y by itself in the last one it is also equal to y=2x-1
For both ways work is attached !
Answer:
It takes 0.145 hours
Step-by-step explanation:
Given:
Distance = 8 miles
Speed = 55 miles per hour
To Find:
Time taken = ?
Solution:
The time taken for an object to travel a particular distance with a average speed can be found by

Now Substituting the given values , we get


Time taken will be 0.145 hours
That will be 295.25 how ?? You multiply 8.75 by 40 then subtract 55.75 =295.25
Convert into like fractions -->
1/3 = 7/21 4/7 = 12/21
7+12 = 19
19/21 is spent therefore he has 2/21 left
