Let the time = x
Let the distance yet to run = y
The first question you have to answer is how many miles has she run in time x?
So far what she has run is (1/12)x
So the distance she has run is 3 - (1/12)*x and that = y
3 - (1/12)x = y <<<<<< answer
50,000,000+6,000,000+900,000+2,000+100+20+6
Answer:
Infinite solutions.
Step-by-step explanation:
If we let x = 1 then y = 3, or if x = 3 y = 5 and so on.
We can substitute any number of values of x and find the corresponding value of y so there are infinite solutions.
Sqrt(21x+1) = x+5
21x + 1 = x^2 + 10x + 25
x^2 - 11x + 24 = 0
(x-3)(x-8) = 0
x = 3 or x = 8
