I need help with this please

Aleonysh [2.5K]

Answer:

x=5

Step-by-step explanation:

First, let's understand logarithms.

When there is no base given, like in this problem's right side of the equation, the base is automatically 10.

So, let's re-write that.

$\frac{7}{x+2}=log_{10}x+5$

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.

$\frac{7}{5+2} =log_{10}(5+5)\\\frac{7}{7} = log_{10}(10)\\1 = 1$

Leya [2.2K]

9514 1404 393

Answer:

a = any positive multiple of 3

Step-by-step explanation:

You want ...

(5 1/3)/(4/a) = whole number

(16/3)·(a/4) = whole number

(4a/3) = whole number

This will be the case for a = 3n, for any positive integer n.
