22<br> Solve for x.<br> 3x - 5 = 10<br> x equals.....<br> help

Answer:

$x = 5$

Step-by-step explanation:

$3x - 5 = 10$

We want to isolate the x.

$3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5$

$3x = 15$

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

$\frac{3x}{3} \;=\;\frac{15}{3}$

$x = 5$

1. |4n-15|=|n|<br> 2. |2c+8|=|10c| <br> can you please show the work for both

Alja [10]

Problem 1

<h3>Answers: n = 3 or n = 5</h3>

---------------

Work Shown:

$|4n - 15| = |n|\\\\4n - 15 = n \ \text{ or } \ 4n-15 = -n\\\\-15 = n-4n \ \text{ or } \ -15 = -n-4n\\\\-15 = -3n \ \text{ or } \ -15 = -5n\\\\-3n = -15 \ \text{ or } \ -5n = -15\\\\n = \frac{-15}{-3} \ \text{ or } \ n = \frac{-15}{-5}\\\\n = 5 \ \text{ or } \ n = 3\\\\$

==============================================

Problem 2

<h3>Answers: c = 1 or c = -2/3</h3>

-----------------------

Work Shown:

$|2c+8| = |10c|\\\\2c+8 = 10c \ \text{ or } \ 2c+8 = -10c\\\\8 = 10c-2c \ \text{ or } \ 8 = -10c-2c\\\\8 = 8c \ \text{ or } \ 8 = -12c\\\\8c = 8 \ \text{ or } \ -12c = 8\\\\c = \frac{8}{8} \ \text{ or } \ c = \frac{8}{-12}\\\\c = 1 \ \text{ or } \ c = -\frac{2}{3}$

How would you solve this question?

RoseWind [281]

Answer:

D) ½

Step-by-step explanation:

∛(x√x) = xᵇ

Cube both sides.

x√x = x³ᵇ

Square both sides.

x² x = x⁶ᵇ

x³ = x⁶ᵇ

Equate the exponents.

3 = 6b

b = ½
