Answer:

Step-by-step explanation:

Recall these rules of logs: log a + log b = log (ab), and log a^b = b log a

Then 3 log q = log q^3 and 6 log v = log v^6, and

log q^3 + 6 log v becomes log q^3 * v^6

Now rewrite this using b as the base:

log q^3 * v^6

Find the missing factor. Write your answer in exponential form. 6^-8 = blank 6^7

Keith_Richards [23]

Answer:

6^ (-15) = x

Step-by-step explanation:

6^-8 = blank 6^7

6^-8 = x* 6^7

Divide each side by 6^7

6^-8 / 6^7 = x 6^7 / 6^7

6^-8 / 6^7 = x

Since the bases are the same, we can subtract the exponents

6^ ( -8-7) = x

6^ (-15) = x

Please Help- K + ⅓ = 5 ⅛ | K = ? Show Your Reasoning.

Answer:

$4\frac{19}{24}$

Step-by-step explanation:

I hope I did this right:

So first thing to do is set up the equation.

$K + \frac{1}{3} = 5\frac{1}{8}$

Next thing to to is subtract 1/3 from both sides to get:

$K = 5\frac{1}{8} - \frac{1}{3}$

Next up, you will multiply each of the fractions by the opposing value

(multiply 1/8 by 3 and 1/3 by 8)

$K = 5\frac{3}{24}$ $-\frac{8}{24}$

Alright almost done, by multiplying 24 by 5 you get 120, that will go in the numerator to make the math a lot easier.

K = $\frac{123}{24}$ $-\frac{8}{24}$

Finally, you subtract 123 over 24 by 8 over 24.

K = $\frac{123}{24} - \frac{8}{24} = \frac{115}{24}$

Then just simplfy the 115/24 to get

$4\frac{19}{24}$

-2x+6=30-6x. -6,6,-8,8

Illusion [34]

-2x + 6 = 30 - 6x
--> -2x + 6x = 30 - 6
--> 4x = 24
--> x = 24/4
--> x = 6
