The answer is A i hope it helps
If his best time is x, and the best time is smaller, then (1+1/3)*x=his second best time. If x+4=his second best time (since his second best time is 4 seconds slower), then (1+1/3)*x=x+4. Multiplying it out, we get (3/3+1/3)*x=x+4
=4x/3=x+4. Subtracting x from both sides, we get 4x/3-3x/3=x/3=4. Multiplying both sides by 3, we get x=12=his best time
Hello Isaiah! (Cool name)
10x - 7y = -8
We need to use the slope - intercept form y = mx + b to find the slope m.
Thus, the slope for this is m= 10/7
I hope this helps!
