you bought a magazine for $5 and four erasers. you spent a total of $25.

Magazine cost: 5$ each

Eraser cost: X$ each

Total cost is the number of items (1 magazine) times the cost of each item (5$). We don't know the cost of each eraser, so we represent that using a variable, X.

1(5) + 4(X) = 25

5 + 4X = 25

subtract 5 from both sides

4X = 25 - 5

4X = 20

divide both sides by 4

X = 20/4

X = 5

Each eraser cost 5$

<em>Each Eraser was equal to 5 dollars.</em>

<em></em>

<em>5 + 4x = 25</em>

<em>-5 on both sides.</em>

<em>4x = 20</em>

<em>/ 4 on both sides.</em>

<em>x = 5.</em>

<em>So your equation is 5 + 4x = 25 and your answer is 5 dollars per eraser.</em>

We are given arc KL is 12x+4, arc KJ is 8x-6, and angle E is 99 degrees. What is the actual degree measure of arc KJ? *
Svetlanka [38]

The  actual degree measure of arc KJ is 99 degrees

<h3>Circle geometry</h3>

From the given informtion

arc KL = 12x+4

arc KJ = 8x-6

<E = 99 degrees

The equation required to get the value of "x" is given as:

12x + 4 + 8x - 6 + 99 = 360

20x + 97 = 360

20x = 360 - 97

20x = 263

x = 13.15

For the arcKL

arcKJ = 8(13.15) -  6

arcKJ = 99degrees

HEnce the  actual degree measure of arc KJ is 99 degrees

What is the inverse function f(x)=2x +1
Neko [114]

The inverse function is f(x) = \frac{x - 1}{2}


You can find the inverse of any function by switching the f(x) value and the x value. Then solve for the new f(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.


f(x) = 2x + 1 ---> Switch the f(x) and x values

x = 2f(x) + 1 ---> Subtract 1 from both sides

x - 1 = 2f(x) ----> Divide each side by 2.

\frac{x - 1}{2} = f(x) ---> Switch the order so that it looks like a function.

f(x) = \frac{x - 1}{2}


And that would be your inverse function.

Which law would you use to simplify the expression (p/q)3? power of a power power of a quotient quotient of powers power of a pr
Sloan [31]

Answer:

power of quotient

Step-by-step explanation:

We have been given an expression  and we are asked to choose the correct rule to simplify our given expression.

Since our given expression is a fraction raised to 3rd power. Power of a quotient rule states when a quotient is raised to an exponent, then the exponent is distributed to both numerator and denominator of the quotient.

Using power of a quotient rule, we will get, (\frac{p}{q} )^3=\frac{p^3}{q^3}
