It walks for 1.6 minutes or 1 min and 36 secs
Answer:
Ed has traveled for 3 hours and 17 minutes, and has 2 hours and 28 minutes left to travel.
Step-by-step explanation:
Given that Ed is on a road trip and he has already traveled 201 miles and is driving at a rate of 61 mph, the equation could be used to find how many hours he has traveled and how many and has left in his road trip traveling 697 total miles is the next:
201/61 = 3.29
100 = 60
29 = X
29 x 60/100 = X
29 x 0.6 = X
17.4 = X
So, Ed has traveled for 3 hours and 17 minutes.
697 - 201 = 496
496/201 = 2.46
100 = 60
46 = 0
46 x 0.6 = X
27.6 = X
Thus, he has 2 hours and 28 minutes to travel.
This is a system of equation:
7y - 5x = 31
x = 4 - 2y
Plug in 4 - 2y for x
7y - 5(4 - 2y) = 31
Distribute -5 to both 4 and -2y
7y - 20 + 10y = 31
Simplify
17y - 20 = 31
Isolate the y. Note the equal sign. What you do to one side you do to the other. Do the opposite of PEMDAS.
Add 20 to both sides
17y - 20 (+20) = 31 (+20)
17y = 51
Divide 17 from both sides to isolate the y
17y/17 = 51/17
y = 51/17 or 3
y = 3
-------------------------------------------------------------------------------------------------------------------
Plug in 3 for y in one of the equations.
x=4−2y
x = 4 - 2(3)
Simplify.
x = 4 - 6
x = -2
-------------------------------------------------------------------------------------------------------------------
x = -2, y = 3 is your answer, or B)
