Answer: x= 10

Step-by-step explanation:

Same side exterior angles sum to 180.

Using this axiom we can say that

142+ (3x+8) = 180

Add like terms on the left side

150+ 3x = 180

Subtract 150 from both sides

3x = 30

Divide both sides by 3

X= 10

How might we know whether x is a positive number, negative number, or zero, without solving the equation? 5x = -16.5​
pochemuha
To be able to get the negative number you have to divide x by a negative number to get your result. Seeing the solution is a negative number but your left side of the equation is a positive number tells us we have to divide by a negative number on the left side and right to give us the solution...

Answer:

2/9

Step-by-step explanation:

The probability of getting any letter once is 1/3

The probability of getting any combinations = 1/3 * 1/3 = 1/9
