\boldsymbol{\mathbf{4 ounces water we need to add.}}

An after shave lotion contains 45% of ethyl alcohol
i.e 100% - 45% = 65% nonalcoholic
As mentioned, we have 8 ounces of fluid and that contains 45% of ethyl alcohol.
![{=\,8}\times{0.45}](https://tex.z-dn.net/?f=%7B%3D%5C%2C8%7D%5Ctimes%7B0.45%7D)
i.e ![\boldsymbol{\mathbf{3.6 ounces alcohol.}}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B%5Cmathbf%7B3.6%20ounces%20alcohol.%7D%7D)
We need fluid which 70% nonalcoholic.
i.e 100 - 70 = 30% of alcohol.
Then there is already 3.6 ounces of alcohol in fluid.
As required, Let consider 3.6 ounce is 30% of alcohol.
70% must be other liquid.
That is equal to =
= ![\boldsymbol{\mathbf{\frac{3.6}{0.3}\times{0.7}}}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B%5Cmathbf%7B%5Cfrac%7B3.6%7D%7B0.3%7D%5Ctimes%7B0.7%7D%7D%7D)
= 8.4 Ounces Of other liquid.
Then total ounces of the lotion is
= 3.6 + 8.4
= 12 ounces.
Water required to add is,
= 12 - 8
= ![\boldsymbol{\mathbf{4 ounces}}](https://tex.z-dn.net/?f=%5Cboldsymbol%7B%5Cmathbf%7B4%20ounces%7D%7D)

Answer:
x = 6
Step-by-step explanation:
10x-5 = 7x+13 1. -7 on both sides
3x-5 = 13 2. +5 on both sides
3x = 18 3. /3 on both sides
x = 6
SAS only
PQ and QR are congruent (given)
QS and SQ are congruent (Reflexive Property)
∠PQS and ∠RQS are congruent (again, Reflexive Property)
Note: It is not SSS, becase we do not have the information (yet) to state that PS is congruent with RS
hope this helps
