Not always it depends on what kind of problem you get. Sometimes you have get a problem that does not have multiplication so then you'd start with division instead.. Get what I'm saying lol? Maybe that helps.
<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
Step-by-step explanation:
P(A or B) = P(A) + P(B) − P(A and B)
P(A or B) = 6/36 + 5/36 − 0/36
P(A or B) = 11/36
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
