To determine the number of days, we need to set up equations relating the given values above. The total distance that Kayla would want to travel is a sum of the total distance she traveled from running and the total distance she traveled from biking. So,
200 miles = (6 miles/day) x + (10 miles/day) y
where x is the number of days she spent running and y is the number of days she spent biking.
If the minimum days she used for biking would be 15 days or y = 15, then
200 miles = (6 miles/day) x + (10 miles/day) (15 days)
Solving for x,
200 = 6x + 150
50 = 6x
x = 8.3333 days
Total number of days = 15 days for biking + 8.3333 days for running = 23.3333 days or about 24 days.
Answer:
The answer would be B. X . 3/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Hope this helps good luck! :)
5x + 2y = 12
-6x - 2y = -14
Add them
-x = -2
x = 2
5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
Answer:
(x2 - 1) - 5x - 1
