Answer:

C

Step-by-step explanation:

First you distribute and multiply both 4x and -5 by 6. This gives you the following equation:

24x-30=42

Next, you add 30 to both sides, giving you:

24x=72

Finally, you divide it all by 24, leaving you with

x=3

An inequality is shown: −np − 4 ≤ 2(c − 3) Which of the following solves for n?
sesenic [268]

Answer:

\huge\boxed{n\leq\dfrac{2-2c}{p}\ \text{for}\ p0}

Step-by-step explanation:

-np-4\leq2(c-3)\qquad\text{use the distributive property}\\\\-np-4\leq2c-6\qquad\text{add 4 to both sides}\\\\-np\leq2c-2\qquad\text{change the signs}\\\\np\geq2-2c\qquad\text{divide both sides by}\ p\neq0\\\\\text{If}\ p0 ,\ \text{then}\\\boxed{n\geq\dfrac{2-2c}{p}}

An axiom in Euclidean geometry states that in space, there are at least two three four five points that do lie in the same plane
Nonamiya [84]

The answer is a space contains at least four points that do not lie in a same plane or not all in the same plane. An axiom is a statement or proposition that is observed as being established, accepted, or self-evidently true. In other words, it is any statement or mathematical statement that functions as a starting point from which other statements are logically derived. So this can be found on postulate 1 that states “a line containing at least two points; a plane contains at least three points not all in one line; and a space contains at least four points not all in the one plane.”

yanalaym [24]

It is NOT possible to determine the missing value from the given data.

<h3>Mean and Median</h3>

Mean is the average of a number of data while the median is the number at the middle of the given data.

  • For a given data with a missing value, we can only find the missing value by calculating the mean of the data and equating the given mean.

Hence from the given data, it is NOT possible to determine the missing value from the given data.
