A school is ordering chairs for the teacher's lounge and some of the classrooms, Each classroom needs 10 chairs, while the teacher's lounge needs 19. Let n represent the number of classrooms included in the order and c represent the total number of chairs. Complete the table using the equation c = 10n + 19.​

Answer/Step-by-step explanation:

To complete the table, substitute the value of n into c = 10n + 19 to get its corresponding value.

Thus:

When n = 6,

c = 10(6) + 19

c = 60 + 19

c = 79

When n = 7

c = 10(7) + 19

c = 70 + 19

c = 89

When n = 9,

c = 10(9) + 19

c = 90 + 19

c = 109

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
