Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5
Answer: 5 packs of Snickers and 2 packs of Kit Kats.
Step-by-step explanation: How? Okay so snickers come in packs of 6 to find the number that will be equal to Kit Kats you must figure out factors. 30 has a factor of 6 and 15. 5 packs of snickers will get you 30 total snickers. 2 packs of Kit Kats will get you a total of 30 Kit Kats. I hope this helped! (:
Do you mean (x=26)? If so, 7 times 26 + 14 +2 times 26 + 3 = 2... i dont know...
To get the answer we can use proportion.
30 ------------- 100%
12 --------------x
crossmultiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - its the percentage of cars which finished the race.
100%-40%=60% - its the answer
