Zoe has 5 pounds of potatos she has multiple recipes that require 3/4 pound of potatoes how many recipes will she be able to mak
Natali [406]
Amount of potatoes that Zoe has = 5 pounds
Quantity of potatoes that Zoe need for each recipe = 5/(3/4) 
                                                                                 = 5 * (4/3) 
                                                                                 = 20/3 
                                                                                 = 6 2/3 
From the above deduction, we can conclude that only 6 recipes can be made. The remaining amount of 2/3 will remain unused. I hope the procedure is clear enough for you to understand.

Charisse is buying two different types of cereals from the bulk bins at the store. Granola costs $2.29 per pound and muesli cost
valentina_108 [34]
Even though im not giving you grapahs, I can explain you the situation and I can shed you light inot this. Pay attention. Giveen the data we are going to use it like this  <span>2.29x + 3.75y <= 7.00. Remember, you can't spend more money than 7.00, so whatever you buy has to be within 7.00$ or equal 7.00$. Since you're buying in pounds, and the amount varies, you have a variable there to indicate the price of each product depending on how many pounds of it you buy. Now, what you need to do is use this equation to graph and also solving part b by substituting in that value for y. I hope this can help you</span>

75 percent of what number is 54
Olin [163]
Ok, this is simple. First put 54 over X in a fraction. 54/x Then put 75 over 100. 75/100 Then you cross multiply. 75(x)= 54(100) Simplify. 75x = 5400 Divide. x=72 Your answer is 72
Hope this helps :)

How do i conjugate the binomial<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B6%20%2B%204%7D%20" id="TexFormula1" title=" \s
leonid [27]
We solve 6 + 4

6 + 4 = 10.

Square root of 10:

\boldsymbol { \sqrt{6 + 4} =  \sqrt{10}  }\\&#10;\\&#10;\\&#10;\boldsymbol {  \sqrt{10}l\underline{ \ 3.16227766017}}\\&#10;\boldsymbol {  \underline{- 10}l \ 3.16227766017 \times 3.16227766017 }\\&#10;\boldsymbol { \ \ \ 00}

<span>The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)

 What is that periodic decimal?
</span>
\boxed{\textbf{3.16227766017} \boldsymbol{ \ \Leftarrow }\textbf{Square root of 10}}

Solve the system of equations.
Sloan [31]

Answer:

b.

( -3, -5)

Step-by-step explanation:

6x + 13 = 2x + 1

6x -2x = 1-13

4x = -12

x = -12/4 = -3

y = 6x + 13

y = 6(-3) +13 = -18+13 = -5

(x, y) = (-3,-5)
