Answer:

x = 101°

Step-by-step explanation:

x and are same- side interior angles and sum to 180° , then

a + x = 180° , that is

79° + x = 180° ( subtract 79° from both sides )

x = 101°

What is the probability that 2 randomly selected months have 31 days?
aniked [119]

Answer:

31.8%

Step-by-step explanation:There are 7 months that have 31 days so,

The odds the first selected month has 31 days is 7/12

The next month there are only 6 months left with 31 days of only 11 months to choose from

so the odds for the second are 6/11

To calculate the odds they BOTH  have 31 months you multiply the two odds:

(7/12) x (6/11) = 42/132 = .318 so 31.8%

He lesson. If the first step in the solution of the equation -x + 6 = 5 - 3x is "subtract 5," then what should the next step be?
Xelga [282]

Answer:

  add x

Step-by-step explanation:

The operation "subtract 5" has eliminated the constant from the right side of the equation, so the next step would be to eliminate the variable from the left side. You do that by adding the opposite of the variable term.

The opposite of the term -x is x, so we "add x" as the next step.

This makes the solution look like ...

  -x +6 = 5 -3x

  -x +1 = -3x . . . . . . subtract 5

  1 = -2x . . . . . . . . . add x

  -1/2 = x . . . . . . . . .divide by -2

_____

<em>Comment on this solution</em>

My preference is always to add the opposite of the variable term with the smallest coefficient. Here, that term is -3x, so I would add 3x as a first step. This leaves the only x-term with a <em>positive</em> coefficient, so can reduce errors in the solution.
