Answer:
1.5 or -5
Step-by-step explanation:
2x²+7x-15=0
Divide by 2:
x²+7x/2-15/2=0
x=-7/2/2 ± √49/4(4)+15/2
=-7/4 ± √49/16+120/16
=-7/4± √169/16=-7/4 ±13/4
=6/4 or -20/4
=1.5 or -5

Answer:
There are 8 220-mililiter servings in the container, with 130 mililiters left over.
Step-by-step explanation:
The mililiter unit of measure refers to 1/1000 liters. So 220 milliliters is actually 0.22 liters. Therefore, to determine the number of 220 milliliter servings that can fit in 1.89 liters, the following division must be performed:
1.89 / 0.22 = X
8.59 = X
Therefore, 8 servings of 220 milliliters (1,760 ml) could be served, with 130 milliliters left over.
