Let x by the number of cooler
since each cooler has 25 bottles
then in total we have 25x
there are 10 friend in total to divide the bottles equally
we have 25x/10 this expresses the number of bottles each friend will get
that answers part a) of the question
now for part b)
we are told the friend brought 2 cooler
then we should have 25(2)=50 number of bottles in total
then it goes that each one of the friend will get 5 bottles (50/10)
Done !
Answer:
x=5
y=2
Step-by-step explanation:
5x + 3y= 31
-6x - 3y = -36 (multiple by -3)
-x=-5
x=5
2(5)+y=12 or 25 + 3y= 31
10+y=12 3y=6
y=2 y=2
Answer:
9
Step-by-step explanation:
You take 3x and subtract it from both sides.
3x-3x+27=6x-3x
You now should have 27=3x. Divide 3 from 27 to get 9 as your total.
Answer:
- 1/65
Step-by-step explanation:
the multiplicative inverse of - 65 is - 1/65
(- 1/65) x (- 65) = 1
the x-intercept of the line 3x - 5y = 7. is (7/3,0)
