Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
3 0

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

Ishaan is 333 times as old as christopher and is also 141414 years older than christopher.
GalinKa [24]
<span>Ishaan is 21, Christopher is 7 No actual question given, but I will assume that the question is "How old are they?". If that's the case, we can create two equations. I'll use I for Ishaan's age and C for Christopher's. I will also assume that there's been some formatting issues here and for some reason, numbers are repeated 3 times without any spaces. So "Ishaan is 3 times as old as Christopher" I = 3C "is also 14 years older than Christopher I = C + 14 Since both equations are equal to each other, let's set them equal. So 3C = C + 14 2C = 14 C = 7 So Christopher is 7. And we can use the equation I = C + 14 to get Ishaan's age. So I = C + 14 I = 7 + 14 I = 21</span>
