PLEASE ANSWER! I WILL GIVE 80+ POINTS, BRAINLIEST, A THANKS, 5 STARS, AND A FOLLOW IF YOU ANSWER ALL OF THESE (P.S they all have to do with direct variation):

#1) If y varies directly with x, write an equation for the direct variation. Then find each value. If y = –4 when x = 10, find y when x = 5

#2) If y varies directly with x, write an equation for the direct variation. Then find each value. If y = 12 when x = –15, find y when x = 2

#3) If y varies directly with x, write an equation for the direct variation. Then find each value. Find x when y = 18, if y = 9 when x = 8.

You got 2 right I think you add 8 to 16 which makes 24 make them whole numbers and get 12 as an answer so r=12

Answer:

p=6 and r=48

Step-by-step explanation:

19=4p-5

19+5=4p

24=4p

24/4=p

6=p

check

19=4p-5

19=4x6-5

19=24-5

19=19

3)r/2-8=16

r/2=16+8

r/2=24

r=24x2

r=48

check

r/2-8=16

48/2-8=16

24-8=16

16=16

The event coordinator asks you to determine how many students participated in the
track-and-field day. The total number of students in seventh and eighth grade
combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth-graders. If 4/8 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.

Answers

Answer:

374.125 students. Not sure if you're supposed to round up or down considering you can't have a fraction of a person, but I would round down.

Step-by-step explanation:

(5/8) (584) = 365 seventh graders in total

(3/8) (584) = 219 eighth graders in total

(4/8) (365) = 182.5 seventh graders who participated in track-and-field day

(7/8) (219) = 191.625 eighth graders who participated in track-and-field day

182.5 + 191.625 = 374.125 students in total who participated

Answer:

First, I took 5/8 out of 584 for the seventh graders which came out to 365 seventh graders. Then, I did the same thing with 3/8 and it came out to 219 eighth graders. Then I took out 4/5 out of 365 which resulted as 292. Then I did the same thing for 7/8 and the results came out as 191. So in total 483 students participated in track-and-field day.

Which equation can be used to find 75 percent of 200?
(A) StartFraction 75 times 1 Over 200 times 1 EndFraction = StartFraction 75 Over 200 EndFraction
(B) StartFraction 100 times 26.7 Over 75 times 2.67 EndFraction = StartFraction 267 Over 200.25 EndFraction
(C) StartFraction 200 times 2 Over 100 times 2 EndFraction = StartFraction 400 Over 200 EndFraction
(D) StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction

Answers

the answer is x= 75*2
x= 3/4*200
and the equations are x= 75/100 *200
= 75*2
or 3/4 * 200
The answer is x=75*2
