Question 8 (1 point)
AleksandrR [38]

Answer:

solution is x=3

Step-by-step explanation:

logx-log3=log(x-2)

apply log property

log a- log b= log a/b

logx-log3=log(x-2)\\log (\frac{x}{3} )=log(x-2)

we have log on both sides

so we remove the log and make the arguments equal

\frac{x}{3} = x-2

solve for x, multiply whole equation by 3

x=3(x-2)\\x=3x-6\\x-3x=-6\\-2x=-6\\x=3

now plug in 3 for x  and check

logx-log3=log(x-2)\\log3-log3=log(3-2)\\0=0

solution is x=3

The sum of two numbers is 18 and the difference is 8
Andrews [41]

Answer:

x = 13 and y = 5

Step-by-step explanation:

x + y = 18

x - y = 8

<u>Step 1:  Find y</u>

x = 18 - y

(18 - y) - y = 8

18 - y - y - 18 = 8 - 18

-2y / -2 = -10 / -2

<em>y = 5</em>

<em />

<u>Step 2:  Plug into x + y = 18 to get x</u>

x + 5 - 5 = 18 - 5

<em>x = 13</em>

<em />

Answer:  x = 13 and y = 5

N - 1/8 = 3/8<br> I am no smort and i forgot to study for a test =|
sdas [7]

Answer:

  • \boxed{\sf{n=\dfrac{1}{2}=0.5 }}

Step-by-step explanation:

Isolate the term of n from one side of the equation.

<h3>n-1/8=3/8</h3>

<u>First, add by 1/8 from both sides.</u>

n-1/8+1/8=3/8+1/8

<u>Solve.</u>

<u>Add the numbers from left to right.</u>

3/8+1/8=4/8

<u>Common factor of 4.</u>

4/4=1

8/4=2

<u>Rewrite as a fraction.</u>

=1/2

n=1/2

<u>Divide is another option.</u>

1/2=0.5

n=1/2=0.5

  • <u>Therefore, the final answer is n=1/2=0.5.</u>

I hope this helps you! Let me know if my answer is wrong or not.
