At Spring Middle School, 25% of the 124 students Mr. Barrett teaches buy their lunches in the cafeteria. How many students do NOT purchase their lunches in the cafeteria?

A. 31 students
B. 68 students
C. 93 students
D. 45 students

C. 93 students

Step-by-step explanation:

25 x 124 = 3100

3100/100 = 31

124 - 31 = 93

Therefore, 93 students do NOT purchase their lunches in the cafeteria.

C. 93 students do not purchase their lunches in the cafeteria.

Step-by-step explanation:

25% * 124= 31  

124 - 31 = 93

how am i supposed to answer

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
