Answer:

-6x +9

Step-by-step explanation:

You're apparently expected to recognize that equation solution processes generally involve eliminating parentheses using the distributive property. When you do this, you get ...

... (-3)(2x) + (-3)(-3)

... = -6x +9

_____

<em>Comment on the question</em>

Depending on the inequaltiy, you may want to divide by -3 first in your solution process. The question seems to assume there is One Right Way. In math, there is not.

Kryger [21]

Answer:

The value of <em>n </em>is 15.

Step-by-step explanation:

The combined proportion is computed using the formula:

P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}

The information provided is as follows:

n_{A}=25\\p_{A}=0.56\\n_{B}=n\\p_{B}=0.60\\P=0.575

Compute the value of <em>n</em> as follows:

P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}

0.575=\frac{25\times 0.56+n\times 0.60}{25+n}\\\\0.575(25+n)=14+0.60n\\\\14.375+0.575n=14+0.60n\\\\0.60n-0.575n=14.375-14\\\\0.025n=0.375\\\\n=15

Thus, the value of <em>n </em>is 15.
