Answer:

13) A

14) B

15) C

16) C

Step-by-step explanation:

13)

Since the total number of seats, 18,000, is a combination of both the field and the grandstand seats, their number needs to be added together. Therefore, the equation is s+7,500=18,000.

14)

If you subtract 56 from both sides of the equation that you are given, you will be left with a=72.

15)

If you divide both sides of the equation by 2.4, you will be left with p=3.15.

16)

If you divide both sides of this equation by 2/3, you will be left with w=(3/4)/(2/3)=9/8 or 1 1/8 pounds. Hope this helps!

Find the missing term.
igor_vitrenko [27]

Equations are used to relate equal expressions.

The missing term is: \mathbf{  m -1}

The equation is given as:

\mathbf{\frac{m - n}{m^2 - n^2} + \frac{?}{(m -1)(m -n)} = \frac{2m}{m^2 - n^2}}

Express \mathbf{m^2 - n^2\ as\ (m - n)(m + n)}

So, we have:

\mathbf{\frac{m - n}{(m - n)(m + n)} + \frac{?}{(m -1)(m -n)} = \frac{2m}{(m - n)(m + n)}}

Multiply through by \mathbf{m - n}

\mathbf{\frac{m - n}{m + n} + \frac{?}{m -1} = \frac{2m}{m + n}}

Collect like terms

\mathbf{ \frac{?}{m -1} = \frac{2m}{m + n} - \frac{m - n}{m + n}}

Take LCM

\mathbf{ \frac{?}{m -1} = \frac{2m - m + n}{m + n} }

\mathbf{ \frac{?}{m -1} = \frac{m + n}{m + n} }

Divide \mathbf{ \frac{m + n}{m + n} }

\mathbf{ \frac{?}{m -1} = 1}

Cross multiply

\mathbf{ ? =(m -1)\times 1}

\mathbf{ ? =m -1}

Hence, the missing term is: \mathbf{  m -1}

What is 300 out of 2,530 as a percent
patriot [66]
In order to get the answer of that, let's understand first that the question can first be presented as a fraction form. So by breaking down the question, we will be able to get the fraction form which is 300/2530. Now in order to get the percent form of that, we simply divide 300 and 2530. The answer to that will result in 0.11858. Now we know for a fact that in order to make a decimal a percentage, we just have to move the decimal point two times to the right. So the answer is 11.858%
