Answer:
Here we can use the relationship:
Distance = time*speed.
When Jose walks, his speed is 4 mph.
Then if he walks for X hours, the distance that he will travel is:
D = 4mph*X
When Jose runs, his speed is 8mph.
Then if he runs for T hours, the distance that he will travel is:
D´ = 8mph*Y
And we know that he travels in total 20 miles, then we must have that:
D + D´= 20mi
This leads to:
4mph*X + 8mph*Y = 20mi
Where X is the time that he walked, and Y is the time that he runed.
Then the equation that represents the different amounts of times that Jose runs and walks is:
4mph*X + 8mph*Y = 20mi
Where we can not really find the solutions for Y and X, because there is only one equation and two variables.
Answer is lots of god Which equation is the inverse of <em>y </em>= 100 – <em>x</em>2?




14 is your answer
hope this helps
Answer:
11 1/5
Step-by-step explanation:
I put into a calculator lol
The answer is C because 12+0.25*12= 15 and .25 of 12 is 3 so 12+3=15 which is what the answer c gives you. Sorry if this is more confusing than helpful.
