Answer: 19 mile
Explanation:
Each track practice = 1 mile
And she had run 17 miles on her own.
After 2 track practices she would have run 17 mile + 2 mile = 19 mile
It's the answer D (63) since 63/3 = 21 and then 21-9 = 12

Step-by-step explanation:
Answer:
One
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Solving systems of equations
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify systems</em>
y = 3x + 5
y = 4x
<u>Step 2: Solve</u>
If we compare the 2 lines, we can see that they both have a different slope. If they had the same slope but different y-intercepts, then they would be parallel and have no solution. We can also see that the 2 lines aren't the same. If they were, then they would have infinite solutions.
∴ the systems should have only one solution.
