Answer:
138 3/8
Step-by-step explanation:
total shampoo used for 555 dogs = 1/4 x 555 = 138 3/8 bottles
So we can subsitute since they all equatl zero
1/2+n=0=2/3+n
1/2+n=2/3+n
subtract n from both sides
1/2=2/3
false statement
therefor there is no solution
D. You times 5y by 8y then 3
3(2-y) + y = 4.50
6 - 3y + y = 4.50
- 2y = -1.5
y = 0.75
3x + y = 4.50
3x + 0.75 = 4.50
3x = 3.75
x = 1.25
answer
x = 1.25 and y = 0.75
