The answer is 1/4 + - 1/2, which equals -1/4 as the answer.
Answer:
3 1/3 km or 3.33 km (to the hundredth)
Step-by-step explanation:
Using the given formula,
estimated distance = v.t = velocity * time,
velocity = 5 km/h
time = 40 minutes =
hours =
hours
Therefore
distance = 5 km/h *
hours = 10/3 km
= 3.33 km approximately
(2n +20) +60 = 90
-60 -60
2n+20= 30
-20 -20
2n=10
divide by two on both sides
n=5
Answer:
84
Step-by-step explanation:
4v^2 - m^2
let v=5 and m=-4
4 * (5)^2 - (-4)^2
4* (25) - (16)
100 - 16
84
