How many positive integer factors of 100 factorial, are multiples of 2 or 3?
1 answer:
100 factorial is 1*2*3*......*100
Number of multiples of 2 less than 100 = 49
Number of multiples of 3 less than 100 = 33
We are double counting those that are multiples of 2 and 3 (or 6)
Number of multiples of 6 less than 100 = 16
49+33-16 =66
There are 66 factors that are multiples or 2 or 3

Answer:
x= -9
Step-by-step explanation:
7(x+2)=-49
divide both sides by 7
(x+2)=-7
subtract 2 from both dies
x= -9
0 solutions
move the x to one side, and the numbers to the other.
12x (-12x) + 32 (-32)= 12 (-12x) - 7 (-32)
12x - 12x = -7 - 32
0 = -39
0 ≠ -39
∴ you have 0 solutions
