pentagon [3]

Answer:

x = 34°

Step-by-step explanation:

To solve for 'x', we will need to use the Supplementary Angles theorem. This states that on a line, all angles must add up to 180°.

We can set up a simple algebraic equation to solve for 'x':

180 = x + 12 + 100 + x  

180 = 112 + 2x  **Combine like terms

68 = 2x **Divide both sides by '2'

x = 34°.

Therefore, the measure of ∠x = 34°.

I need help answering this question.
Darina [25.2K]
Her credits need to be AT LEAST EQUAL TO OR GREATER THAN 144 (credit hours) so we can eliminate choices B and D.

She already completed 4 semesters in which she receives 15 credit per semester.

This expression can be written as 4(15).

She needs to do a certain remaining hours of credit which can be represented by c and only c without any other coefficient.

So, the most reasonable choice here is A.

Liam is setting chairs for meeting he arranges chairs in 5 rows of the same length he has 3 chairs left over if he arranges the
Rina8888 [55]

Answer:

The answer to your question is 48 chairs

Step-by-step explanation:

Data

5 rows- 3 chairs left over

3 rows - 21 chairs left over

Process

1.- Write two equations each for each situation

x = number of rows

y = number of chairs

Equation 1       y = 5x + 3

Equation 2      y = 3x + 21

2.- Solve the system by equality

                      5x + 3 = 3x + 21

                       5x - 3x = 21 - 3

                               2x = 18

                                 x = 18/2

                                 x = 9

3.- Find the total number of chairs

y = 5(9)+ 3                         y = 3(9) + 21

y = 45 + 3                          y = 27 + 21

y = 48                                y = 48

4.- Conclusion

There are 48 chairs
