Answer:
C
Step-by-step explanation:
4x + 3 = x + 3x + 5
4x + 3 = 4x + 5 //-4x on both sides
3 = 5 //Since the statement is false, it's no solution.
If, it had 3 = 3 or any number n = n, the solution would be infinite. But, if x is equal to any number n, x=n, it would have only one solution.
//Hope it helps
D=M/V. You just multiply both sides by D to get DV=M, then divide V by both sides.
A. pat x-10 is a negative
Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
