67. If mn + p = m + 3n, what is the value of m when n = 4 and p = 6? MP 2
A -2
B
2
C 3
D 3.6
O E 6

B) 2

Step-by-step explanation:

Step 1: Plug in the values of n and p.

Step 2: Subtract m from both sides.

Step 3: Subtract 6 from both sides.

Step 4: Divide both sides by 3.

Step 5: Check if solution is correct.

Therefore, the answer is B) 2.

No

Step-by-step explanation: The set of counting numbers {1, 2, 3, 4, ...} is called the set of natural numbers. The natural numbers begin with 1 and go on indefinitely.

Decimals are not natural numbers unless they have a 0 after the decimal point that repeats. However, 2.8 does not so it's not natural.
