7 1/2 * 2 = 15
The 3rd hour was 1/4 of the total distance in 3 hours.
1/4 = 0.25 as a decimal, and 25% as a percent.
15 (0.25) = 3.75
15 + 3.75 = 18.75
0.75 = 3/4 as a fraction.
So, he cycled 18 3/4 miles in 3 hours.
I hope this helps, and I am sorry if I get this question wrong. (which is in all likelihood)
Answer:
The "zeros" of the quadratic equation occur when f(x) (or "y") equals zero. The place on the graph where y = 0 is the x-axis. So the zeros are the same as the x-intercepts. we can see that we are multiplying two linear factors together and the result is zero.

Average acceleration: ( v - v o ) / Δ t
v = 0 m/s, v o = 20 m/s, Δ t = 3.5 s
a (average) = ( 0 m/s - 20 m/s )/3.5 s = - 20 m/s / 3.5 s =
= - 5.7142857 m/s² ≈ - 5.71 m/s²
Answer:
x = -12
Step-by-step explanation:
Let's solve your equation step-by-step.
8+x=−4
Step 1: Simplify both sides of the equation.
x+8=−4
Step 2: Subtract 8 from both sides.
x+8−8=−4−8
x=−12
