Hello! :)

Answer:

$\boxed{X=-2}$

*The answer must have A NEGATIVE SIGN ONLY!*

Step-by-step explanation:

First, you subtract by 15 from both sides of an equations.

$3x+15-15=8x+25-15$

Subtract numbers from left/right.

$25-15=10$

$3x=8x+10$

Then, you subtract by 8x both sides of an equation.

$3x-8x=8x+10-8x$

Simplify.

$-5x=10$

Divide by -5 from both sides of an equation.

$\frac{-5x}{-5}=\frac{10}{-5}$

Divide by the numbers from left/right.

$10/-5=-2$

$\boxed{X=-2}$ , is the CORRECT/FINAL ANSWER!

Hope this helps you!

Have a nice day! :)

Explain how combining like radicals is similar to combining like terms.

pickupchik [31]

Answer:

Just like combining like terms with the same variables, you combine like

radicals with the same number under the radical signs.

Step-by-step explanation:

Example:

3x + 2x

= 5x {combined like terms}

3√2 + 2√2

= 5√2 {combined like radicals}

Let's take an mathematical example

Let's find the ratio of volume of a cone and cylinder if radius and height are same for both .

See

V for cone=1/3πr²h
V for cylinder=πr²h

The ratio is 1:3

Jamie ordered 200 business cards and paid $23. She ordered 500 business cards a few months later and paid $35. Write and solve a

Gnesinka [82]

Answer:

To purchase 700 business cards, Jamie needs to pay $43.

Step-by-step explanation:

We are given that Jamie ordered 200 business cards and paid $23 in total.

We are also given that Jamie ordered 500 business cards and paid $35.

We can use the rate of change formula to find the average change.

$\displaystyle \bullet \ \ \ \frac{\triangle y}{\triangle x}$

This can also be represented with:

$\displaystyle \bullet \ \ \ \frac{y_2-y_1}{x_2-x_1}$

Therefore, we need to identify our variables.

In every relationship, there is a dependent variable and an independent variable.

The independent variable is the variable that an experimenter adjusts in order to receive an altered effect from an output.
The dependent variable is the variable that adjusts based on the changes made to the independent variable.

We change the amount of business cards that are purchased, which in turn, changes the price.

The y-variable is assigned to the dependent variable and the x-variable is assigned to the dependent variable.

Therefore, if we use the coordinate system:
