Solve 12x-5>-2 please
Stells [14]

Answer:

x >  \frac{1}{4}

Step-by-step explanation:

12x - 5 >  - 2

Lets add +5 in both the sides.

=  > 12x - 5 + 5 >  - 2 + 5

=  > 12x > 3

Now lets divide 12 on both the sides.

=  >  \frac{12x}{12}  >  \frac{3}{12}

=  > x >  \frac{1}{4}

A 6 sided number cube is tossed. what is the probability of rolling a 6 or an odd number?
Veronika [31]
For any probability the formula is P_{desired}=\frac{desired}{total}. In this case we have 4 desired outcomes (the odds, 1, 3 and 5, and also 6) out of 6 total sides, so our probability P_{oddor6} =\frac{odd or 6}{total sides}=\frac{4}{6} = \frac{2}{3}.

Mutually exclusive means the events cant occur at the same time. In our case it is not possible to roll both a 6 and an odd number at the same time since 6 is even. Therefore the events ARE mutually exclusive. 

Combine the two parts and C is the correct answer.  <span />

80 = 210x + 38

42 = 210x

0.2 = x
