You must solve for p, in order to solve for p you must move all the terms to equal p, so the equation is
$2m + 2p = 16$
first move the 2m, subtract the 2m from both sides
$2m + 2p = 16 \\ - 2m \: \: \: \: \: \: \: \: - 2m$
the 2m and -2m cancel out and now your equation looks like
$2p = 16 - 2m$
now to leave p by itself you must divide by 2 on both sides as the 2 is being multiplies on the p (opposite)
$\frac{2p}{2} = \frac{16 - 2m}{2}$
now to put the answer is simplest form your answer is
$p = 8 - m$
which is the first answer choice

A car dealership is having a sale in which customers pay 85% of the retail price for a new vehicle. keith is buying a vehicle wi

mash [69]

First, we calculated the discounted price which would have been paid by Keith. That is the product of 85% and $36,000.
($36,000) x (85%) = $30,600
Then, after negotiating to pay 9% off the sale price, he will only need to pay 91% of the sale price. The new price would be,
($30600) x (0.91) = $27846
Thus, Keith will only need to pay $27,846.

The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving th

USPshnik [31]

Answer:

C) There is not sufficient evidence to support the claim that the mean attendance is greater than 523.

Step-by-step explanation:

Let μ be the the average attendance at games of the football team

The claim: the average attendance at games is over 523

Null and alternative hypotheses are:

$H_{0}$ : μ=523

$H_{a}$ : μ>523

The conclusion is failure to reject the null hypothesis.

This means that test statistic is lower than critical value. Therefore it is not significant, there is no significant evidence to accept the alternative hypothesis.

That is no significant evidence that the average attendance at games of the football team is greater than 523.
