The value of x is 
Explanation:
The expression is
Adding
to both sides of the equation, we get,

Using log definition, if
then
, we have,

Using exponent rule,
,

Simplifying, we have,

Dividing both sides by 9, we have,

Simplifying,

Thus, the value of x is 
Use sin to calculate. Sin30=5/x. Sin=opposite/hypotenuse. Cross multiply. Sin30x=5. x=5/sin30. x=10.
Answer:

Step-by-step explanation:
As the six-sided number cube had six sides, there are six events which could occur. There is only one interger less than 2 (1), therefore the probability of rolling a number less than 2 is
.
There are two events which could occur when flipping a coin. This means the probability of flipping heads is
.
To find the probability of both of these happening, you must multiply the fractions together by multiplying together both the denominators and numerators, therefore:
×
= 
2/a-1 is 100% the correct answer
