dangina [55]

Answer:

$7,000

Step-by-step explanation:

Let $x$ equal the original price.

$12,000+2000=2x$

Combine like terms.

$14,000=2x$

Divide by the coefficient of $x$ , which in this case is $2.$

$7,000=x$

If you like the variable on the left, rewrite:

$x=7,000$

What is the solution to the linear equation?

antoniya [11.8K]

Answer:

$\large\boxed{p=1}$

Step-by-step explanation:

$\dfrac{2}{5}+p=\dfrac{4}{5}+\dfrac{3}{5}p\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{2}{5\!\!\!\!\diagup_1}+5p=5\!\!\!\!\diagup^1\cdot\dfrac{4}{5\!\!\!\!\diagup_1}+5\!\!\!\!\diagup^1\cdot\dfrac{3}{5\!\!\!\!\diagup_1}p\\\\2+5p=4+3p\qquad\text{subtract 2 from both sides}\\\\5p=2+3p\qquad\text{subtract 3p from both sides}\\\\2p=2\qquad\text{divide both sides by 2}\\\\p=1$

LenaWriter [7]

Part A. Express the original claim in symbolic form.

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.

Therefore, the original claim in symbolic form is:

ANSWER:

$\mu=68.9\text{ bpm}$

Part B. Identify the null and alternative hypotheses.

$\begin{gathered} H_0\colon\text{ }\mu=68.9\text{ bpm} \\ H_1\colon\mu\ne68.9\text{ bpm} \end{gathered}$ $\begin{gathered} H_0\text{ or the null hypothesis will be based to our claim. We will test if the mean pulse} \\ \text{rate of an adult male is equal to 68.9 bpm.} \\ H_1\text{ or the alternative hypothesis is the one that contradicts the null hypothesis. That is } \\ \text{why our H}_a\text{ has the sign of not equal to (}\ne). \end{gathered}$
