The velocity (v) is distance (d) divided by time (t):
v = d/t
v = 60 mph
t = 3 1/2 h = 3.5 h
d = ?
d = v * t
d = 60 * 3.5 = 210 mi
5x = x^2 + 4
x^2 - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, 1
(x + 6)^2 = 100
x + 6 = +/1 sqrt100
x + 6 = +/- 10
x = 4, -16
Answer: 5 Erasers
Step-by-step explanation: It's quite simple, really. You divide 20 by 4, (the number of pencils and the ratio number) and then you multiply whatever the quotient was by the ratio number for erasers.
I would say D because 15 to -9 would be going down 24.
