You need 3 sticks of butter for every 24 cookies you bake. How many sticks of butter for 16 cookies
Kay [80]

Answer: 2 sticks.

Step-by-step explanation:

Given statement: You need 3 sticks of butter for every 24 cookies you bake.

Using unitary method , the number of sticks of butter used to bake 1 cookie=\dfrac{3}{24}=\dfrac{1}{8}

Then the number of sticks of butter used to bake 1 cookie=\dfrac{1}{8}\times16=2

Hence, the number of sticks of butter used to bake 16 cookies= 2

Evaluate x-y/5 when x is 23 more than 3 times y and y=6
posledela

Answer:

7

Step-by-step explanation:

1) "x is 23 more than 3 times y" is the same thing as "x = 23 + 3y"

REMEMBER: when you see "is" replace is with an equals sign.

2) Solve for x with your new equation.

3) Plug 6 into the y ("y = 6")

x = 23 + 3 x 6... x = 23 + 18... x = 41

4) Plug in your variables, and evaluate.

(41 - 6)/5... 35/5... 7!

Help please:Suppose that x and y inversely, and x=10 when y=8 write the function that models the inverse variation
jarptica [38.1K]

SOLUTION

From the question, we are told that y varies inversely as x

This is mathematically written as

\begin{gathered} y\propto\frac{1}{x} \\ \propto\text{ is a sign of proportionality } \end{gathered}

Now, we will remove the proportionality sign and replace it with equal to sign =

If we do this, we will intoduce a constant k

\begin{gathered} y\propto\frac{1}{x} \\ y=k\times\frac{1}{x} \\ y=\frac{k}{x} \end{gathered}

So we have the formula

y=\frac{k}{x}

We will substitute the values of x for 10 and y for 8 into the formula to get k, we have

\begin{gathered} y=\frac{k}{x} \\ 8=\frac{k}{10} \\ k=8\times10 \\ k=80 \end{gathered}

Now, we will substitute k for 80 back into the formula to get the inverse function, we have

\begin{gathered} y=\frac{k}{x} \\ y=\frac{80}{x} \end{gathered}

Hence the answer is option C

What is the value of y if log &lt;base 5&gt; &lt;index -7&gt; = y?​
Dvinal [7]

Answer:

Hence, the value of y is undefined.

Step-by-step explanation

log_{5} (-7) = \frac{log(-7)}{log(5)} from the property, log_a (b) = (log(a))/log(b).

The value log (-7) was not defined. So, the entire log value also not defined.

Hence, the value of y is undefined.
