Answer:
The 1st and the last options
Step-by-step explanation:
5:10 can be simplified to 1:2. Other figures that fit this ration are A, or 2:4, and D, or 4:8.
Start with 21 cups , substract 5.5 (5 and one half) , 2.25( 2 and one fourth), and then divide by two (divided into 2 equal portions) and the result is 6.625 and if you divide the options as an improper fraction, you'll get 6 and five eights... so your answer is D.
Answer:
1. D
2. H
3. D
Step-by-step explanation:
1. It is y=mx+b m is slope and b is Y intercept
2. You make it to be in y=mx+b you find the slope and you find where Y is
3. An easy but tedius way is to go to all and plug in the numbers (x,y) or you can first find the slope with the slope formula
Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed

2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer
-2m + 4 = 10
-2m = 6
m=-3
M would be -3
