Answer:
Y= 1.5x
Step-by-step explanation:
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
I hope this will help
Answer:
Rosa is right.
Step-by-step explanation:
Because 3/4 = 0.75
which means 0.75 is greater than 0.25
Answer:
Maura runs at a pace of a 15 minute mile. Ava runs at a pace of a 16:40 minute mile. Maura runs faster.
Step-by-step explanation:
To get this answer I divided 1.25 by 5 which is .25. Then if you divide 60 minutes by .25 the answer is 15 minutes making her run at a pace of 15 minutes per mile. I did a similar calculation for Ava. I divided 50 by 3 which gave me 16.6667. Then i figured out what 2/3 of a minute was, which is 40 seconds. That led me to the conclusion that Ava runs at a pace of 16:40.
hope this helps!!
Answer:
Inconsistent - TRUE
Step-by-step explanation:
A system of linear equation is said to be inconsistent if it has no solution. that is from the graph, the lines does not intersect compared to a consistent equations that has solutions and intersect on the graph.
From the written augmented matrix = ( 0)
( 0)
( 0)
( 5)
( 0)
from the second row of the matrix, it is evident that it has no solutions hence INCOSISTENT

Answer: 250</h3>
==================================================
Explanation:
x = speed of the plane in mph
x-180 = speed of the car, since its 180 mph slower than the plane
For the plane, we can form the equation
distance = rate*time
d = r*t
500 = xt
t = 500/x
For the car, we can say,
d = rt
140 = (x-180)t
140 = (x-180)*(500/x)
140x = 500(x-180)
140x = 500x - 90,000
140x - 500x = -90,000
-360x = -90,000
x = (-90,000)/(-360)
x = 250
The speed of the plane is 250 mph
-----------------------------
Extra info:
The car's speed is x-180 = 250-180 = 70 mph
It takes the plane t = d/r = 500/250 = 2 hours and it takes the car t = d/r = 140/70 = 2 hours. Both vehicles travel for 2 hours, which helps to confirm the answer.
