Answer:
B. -1/3
Step-by-step explanation:
take how far the x's are and you get two to the left (-2) and do the same for the y's and you get six going up (6). if you put that into a fraction and get -2/6 and simplify it you get -1/3
One-half (80) because the answer to that would be 40 and the answer to the question would be 34.2
Depending on the size of the track but from what I know, they are normally 400 meters for 1 lap. All you need to do is 5000 divided by 400 which is 12.5 so 5000 meters is 12 and a half laps around the track.
I think it’s A I may be wrong tho
Let the number of red, black, green and blue balls be R, B, G, U respectively.
B=R (There are as many black balls as red balls)
G+R=10 so G=10-R (Green balls and red balls should add up to 10)
R+10=U (There should be 10 more blue balls than red balls)
The minimal number of balls is 2, 304 so we have the following inequality:
R+B+G+U≥ 2,304
R+(R)+(10-R)+ (R+10)≥2,304
4R≥2,304
R≥2,304/4=576 so R=576
Answer: 576
