Answer:
I think it's D. The independent variable is the length of the race. The dependent variable is the time.
Step-by-step explanation:
Here I'm quoting user kaylaj051903 "because an independent variable is something that is constant and does not change throughout the problem. The dependent variable depends on the independent variable. The race is a 5K race. That will not change. What will change is how long it takes Stephanie to run the 5K race."
X = Ishaan
y = Christopher
3y = x
x = y + 14 Put the first equation into the second.
3y = y + 14
2y = 14
y = 7
Christopher is 7
Ishaan is 21
6² ÷ 2 × 3 + 4
=36/2(3)+4
=(18)(3)+4
=54+4
=58
