Answer:

We have 12 mL of 11% alcohol.

How much water do we add to make it a 6% solution?

We have 1.32 mL alcohol and 10.68 mL water

x is the water to add

(1.32) / (12 + x) = .06

1.32 = .72 + .06x

.6 = .06x

x = 10 mL

Answer:

  72 +13n = 163

  7 nights

Step-by-step explanation:

At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:

  equation: 13n +72 = 163

__

To solve this, we can subtract 72, then divide by the coefficient of n.

  13n = 91 . . . . . . subtract 72 from both sides

  n = 7 . . . . . . . . divide both sides by n

Mario read 7 nights.
