Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.
Answer:

±
√
21
Explanation:
To find

Step-by-step explanation:
Answer 9/7 = 3/4 & 10/25= 2/5
Just split it in half and get 91,000 and put it on each side of the bar graph. 91,000 plus 91,000 equels 182,000
It follows from the definition of the binomial coefficient:

So we have

That is,
gets absorbed into the numerator's factorial, and we introduct
into the denominator. Now,
, so we get

as required.
