You can just pick any 5 digit decimal and multiply it with any 4 digit decimal to check.

You will see that it has 9 digits after the decimal.

The product of a 5 decimal-digit number by a 4-decimal digit number will have 8 digits after the decimal. For example:
0.12345 × 0.1234 = <span>0.01523373 </span>←8 digits
<span>However, we are multiplying with a whole number and a decimal, we will get 9 digits. Therefore, the answer to your query is 9. Hope this helps and have a great day!</span>

A person’s theoretical maximum heart rate (in heartbeats per minute) is 220 - x where x is the person’s age in years (20 ≤ x ≤ 6
Lyrx [107]

Let f(x) represents the heart beat of the person.

Now, we have been given that person’s theoretical maximum heart rate is given by  220 - x.

Also, we have been given that person strive for a heart rate that is at least 50% of the maximum. At least means greater than equal to.

Thus, we have

f(x)\geq (220-x)0.5\\&#10;f(x)\geq 110-0.5x

Also, we have been given that person strive for a heart rate that is at most 75% of the maximum. At most means less than equal to.

f(x)\leq (220-x)0.75\\&#10;\\&#10;f(x)\leq 165-0.75x

Therefore, the system of inequality is given by

f(x)\geq 110-0.5x\\&#10;f(x)\leq 165-0.75x

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\huge x=-6

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Solving for 'x'...}}\\\\-8x-4(x-4)=88\\-------------\\\rightarrow -8x-4x+16=88\\\\\rightarrow -12x + 16 = 88\\\\\rightarrow -12x + 16 - 16 = 88 - 16\\\\\rightarrow -12x = 72\\\\\rightarrow \frac{-12x=72}{12}\\\\\rightarrow  \boxed{x=-6}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
