$the \: lcm \: of \: 2 \: and \: 9 \: is \: 18.so \: the \: lcd \: is \: 18 \\ \frac{11}{2} = \frac{11 \times 9}{2 \times 9} = \frac{99}{18 } \\ \frac{1}{9} = \frac{ 1\times 2 }{9 \times 2} = \frac{2}{18} \\ \frac{99}{18} > \frac{2}{18}$

Simplify 12x + 8x - 3x

Pie

when two numbers have the same variable, we can add and subtract just like normal numbers.

12x + 8x = 20x - 3x = 17x

You roll a number cube twice. Find the probability of the events. Rolling an odd number 2 or a 4.

forsale [732]

Answer: see below

Step-by-step explanation:

If this is a 6 sided die then the only possible roll that isnt an odd, a 2, or a 4 is 6.

The probability of something happening is also the probability of something not happening. So in order to not roll an odd, a 2 or a 4 in two rolls, you have to roll a 6 twice.

P = 1 - (1/6)(1/6) = 1 - (1/36) = (35/36)
