It says to simplify so number 3 would be 12

Number 4 is

Number 5 is
Answer:
Both
Step-by-step explanation:
22/7 is the fraction version of pi
Answer:
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25. The second useful rule is the Sum Rule.

Substract '-3.4x' at LHS nad the RHS of the above expression.

Add '4' on both LHS and RHs of the above expression.
Answer:
The missing angle is 41 degrees
Step-by-step explanation:
First of all, a triangle is measured at 180 degrees in total
To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.
47+92=139 degrees
Next just subtract 139 from 180 to get your answer.
180-139=41 degrees
The answer is 41 degrees
