Hello!
LCM stands for "Least Common Denominator."
The LCM is the smallest common multiple of two numbers.
To find the LCM of 6 and 8, follow these easy steps.
1. Find the prime factorization of both numbers.
6 = 2 × 3
8 = 2 × 2 × 2
Next, multiply each factor the number of times we did above.
LCM = 2 × 2 × 2 × 3
LCM = 24
ANSWER:
The LCM of 6 and 8 is 24.
Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
The formula to calculate the experimental probability is "P(event) = Number of times event occurs/total number of trials"
The expiramental probability should be the fraction "21/47"
The theoretical probability should be the fraction "1/3" because the formula for theoretical probability is the number of favorable outcomes (5 dollar bill) over the total number of possible outcomes (10-dollar bill, one dollar bill, & 5 dollar bill). therefore, there is 1 favorable outcome, and 3 possible outcomes = 1/3.
