Answer:
Option B.
Step-by-step explanation:
The given expression is
We need an expression Which represents the same solution as the given expression.
It can be written as
![(4)[-(3+\dfrac{1}{8})]](https://tex.z-dn.net/?f=%284%29%5B-%283%2B%5Cdfrac%7B1%7D%7B8%7D%29%5D)
![(4)[-3-\dfrac{1}{8}]](https://tex.z-dn.net/?f=%284%29%5B-3-%5Cdfrac%7B1%7D%7B8%7D%5D)
Since is equivalent to given equation, therefore this equation represents the same solution as the given expression.
Hence, option B is correct.
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
