Answer:
x=3, y= - 2
Step-by-step explanation:
4x + 3y = 6
x-3y= 9
x=9+3y
4.(9+3y)+3y=6
36+12y+3y=6
15y = - 30
y = - 2
=> x= 9+3y
x= 9+ 3.(- 2)
x= 3
Answer:
0.00166 dollars per milliliter
0.002142857142857 dollars per milliliter.
Step-by-step explanation:
1. 2.5 carton
2.5 liters of juice is 4.15
2.5 liters=2,500 milliliters
To find the price per milliliter, we will divide the cost by the amount of juice there is.
4.15/2,500=0.00166 dollars per milliliter
2. 6 350-ml cartons
6 350-milliliter boxes= a total of 6*350 ml=2100 milliliter
Again, we will divide the cost by the amount of juice.
4.50/2100=0.002142857142857 dollars per milliliter.
Answer:
Y x 3 - 3 = Y + 57
30 would be your answer
add 3 to both sides so it becomes Y x 3 = Y + 60 and 60/2=30
30 x 3 = 90-3=87
30 + 57 = 87
