Just write it like this: 8 X c=8c (c=cost per shirt), 8c=m total cost of shirts.

NO. Just numbers written down haphazardly.

Sorry, everyone is out of town.  Happy Thanksgiving !

A rice recipe serves 14, but you only need 6 servings. What is the conversion factor?

You have 14, but you will get 6:

 \(\begin{array}{rcll} 14 \cdot \frac{1}{14} \cdot 6 &=&6\\ 14 \cdot \frac{6}{14} &=&6 \end{array} \)

The conversion factor is  \(\frac{6}{14}\) or  \(\frac{3}{7}\)

False.

\((\frac{1}{64})^{5/6} \rightarrow(\frac{1}{64^{1/6}})^5\rightarrow(\frac{1}{2})^5\rightarrow \frac{1}{32}\)

....or 3/7   or 0.42857

(1/64)^5/6=32 true or false

FALSE=1/32

False.

=.03125

pff sorry - if you need 6 you will need the smaller conversion factor

so you times 6/14

14/6

I have no idea what that is either !    Did you type it correctly?

Irving has 10% as many quarters as nickels. If Irving has $5.25 in quarters and nickels, how many nickels does he have?

x = nickels ( 0.05 Cent)

y = quarters(0.25 Cent)

\(\small{ \begin{array}{rcll} $ 5.25 &=& $0.25 y + $0.05 x \qquad & | \qquad y = 10 \% \cdot x\\ $ 5.25 &=& $0.25 \cdot ( 10 \% \cdot x ) + $0.05 x \\ $ 5.25 &=& $0.25 \cdot ( \frac{10}{100} \cdot x ) + $0.05 x \\ $ 5.25 &=& \frac{$0.25 \cdot10}{100} x + $0.05 x \\ $ 5.25 &=& $0.025 x + $0.05 x \\ $ 5.25 &=& $0.075 x \\ $0.075 x &=& $ 5.25 \\ x &=& \frac{$5.25}{ $0.075 }\\ x &=& 70 \end{array} }\)

He has 70 Nickels and 7 Quarters.

70 * 0.05 + 7 * 0.25 = $5.25

Total:    25q + 5n = 525          where q = number of quarters, n = number of nickels

Also:    q = 0.1n                  number of quarters = 10% number of nickels    (10% = 0.1)

Replace q in the first equation by 0.1n:      

25*0.1*n + 5n = 525  or

2.5n + 5n = 525 or

7.5n = 525 so

n = 525/7.5  or 

n = 70

There are 70 nickels.

2\7=5\x

Then x=7*5\2

           =17.5

ok it takes four quarters to make a dallor. then all you do is mulitply 5 to 4 which give you 21 quarters then mulitply it by 10 (in 10%) then divide by 5 (for the nickels). you get 4.20

20% = 0.2

$400*0.2 = 80

In 2010 a town had 10,500 people. It went up to 12,750 in 2015.

\(\begin{array}{rcl} \text{Point 1 } (2010, 10500) \\ \text{Point 2 } (2015, 12750) \\ \\ \hline \\ \text{slope } &=& \dfrac{12750-10500}{2015-2010} \\\\ \text{slope } &=& \dfrac{2250}{5} \\\\ \text{slope } &=& 450\ \frac{ \text{people}}{ \text{year} } \end{array}\\ \)

The number three is waaaayyyyy too hard to wrap, you wont be able to wrap it in time for christmas. put it in a box and wrap both of them together instead.

3-x  cannot be simplified.
