Step-by-step explanation:
speed = distance/time
time = t = distance/speed
t = 180/b + (400-180)/c = 180/b + 220/c = 20(9/b + 11/c)
Answer:
If the lines are parallel, final form of his solution is
b) -5 = -5+1
Step-by-step explanation:
As the options are not given in the question and the question is incomplete, lets complete the question first.
Giovani solves a system of linear equations algebrically, he concludes that the lines are parallel. Which could be his final answer.
a) -5 = -5
b) -5 = -5+1
c) 11 = 11
d) 5 = 5
We know that parallel lines never cross at any point, there is no intersection point, which eventually means that there is no solution to the given equations. A system of equations which have no solution is called an inconsistent system of equations, and it graphs the parallel line.
From the options we can clearly see that only (b) has no solution, while all the rest of the options have solutions. Hence, -5 = -5+1 represents parallel lines.
Answer:
60WPM
Step-by-step explanation:
120/2 = 60
Answer: 8:9
Step-by-step explanation: Two find this answer, you need to see what will be the greatest number they can divide by (greatest common divider), it needs to be the same number for both 18 and 16. What number can go into both numbers, and is the greatest number? The answer is two, now you divide 2 by 18 and 16, so you'll get 8:9.
Hope this helps have a BLESSED and wonderful day! :-)
