PLEASE DON'T GUESS I NEED TO GET THIS RIGHT!!!!!!!!!Bob and his best friend Bill have the same birthday, but Bob is 3 years older than Bill. Let the variable x represent Bob’s age and y represent Bill’s age. Which equation models the relationship between Bill’s age and Bob’s age?
A. y = x/3
B. y = x + 3
C. x = y + 3
D. y = 3x

Answers

Well if Bob (represented by x) is three years older than Bill (y), the only one correct is x=y+3. Dividing by three wouldn't make sense (choice A), adding three more years onto Bob won't work (choice B), and multiplying Bob's age by three wouldn't work either (choice D). The answer is choice C. 
x=y+3

The least common multiple of 3, 4, 6, and 8 is
A. 72.
B. 24.
C. 96.
D. 8.

Answers

Answer:

B. 24

Step-by-step explanation:

The least common multiple  of two numbers is the smallest number

that is a multiple of  all the numbers ( except 0)

Let us look at the multiples of the numbers given:

The multiples of 3,4,6 and 8 are:

3:    3,6,9,12,15,18,21,24.

4:    4,8,12,16,20,24.

6:     6,12,18,24.

8:    8,16,24.

24 is the smallest number that is a common multiple of all the numbers.

The least common multiple of 3, 4, 6, and 8 is 24.

The least common multiple of 3, 4, 6, and 8 is 24.

List the multiples out:

3: 3, 6, 9, 12, 15, 18, 21, 24
4: 4, 8, 12, 16, 20, 24
6: 6, 12, 18, 24
8: 8, 16, 24
