Answer:
It will take Josie 80 minutes to run 10 miles.
Step-by-step explanation:
We can set up a proportion between the number of minutes she runs to the number of miles she runs. From what we know in the equation, we know that it takes her 24 minutes to run 3 miles, and it takes x minutes to run 10 miles. We can represent this in a proportion!
We know that the ratio of 24:3 will be the same for any number of miles, so we can say
We can solve this by first simplifying the left hand side then isolation x by multiple both sides of the equation by 10.
24/3 = 8
8 = ![\frac{x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D)
80 = x
It will take Josie 80 minutes to run 10 miles.
Answer:
D
Step-by-step explanation:
8 is LESS THAN 1/2x
so youd take those numbers and multiply by 1/2
C, B, and A are all under 8, so that would be wrong
when you multiply 1/2 with 17, you get 8.5 which is bigger than 8. then everything else above that is more than 8, therefore D is the right answer.

Answer:
Answer: x equals to 2 and -5
Step-by-step explanation:
![{ \tt{ {x}^{2} + 3x - 10 = 0 }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%20%7Bx%7D%5E%7B2%7D%20%2B%203x%20-%2010%20%3D%200%20%7D%7D)
» Factorise the equation quadratically:
![{ \tt{(x - 2)(x + 5) = 0}} \\ { \tt{x = 2 \: \: and \: \: - 5}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%28x%20-%202%29%28x%20%2B%205%29%20%3D%200%7D%7D%20%5C%5C%20%7B%20%5Ctt%7Bx%20%3D%202%20%5C%3A%20%20%5C%3A%20and%20%5C%3A%20%20%5C%3A%20%20-%205%7D%7D)
