Step-by-step explanation:
We calculate as follows:
15 mL pure ethanol / 100 mL solution (400 mL) = 60 mL pure ethanol
32% = 32 mL pure ethanol/100 mL solution = 60 mL pure ethanol + x mL pure ethanol / (400 + x)
x = 100 mL pure ethanol was added to the solution ------> OPTION D
Answer:
Step-by-step explanation:
1. y - 2 = -3(x - 4)
y - 2 = -3x + 12
y = -3x + 14
2. y - 6 = -1/2(x + 5)
y - 6 = -1/2x - 5/2
y - 12/2= -1/2x - 5/2
y = -1/2x + 7/2
