STRUCTURE Gustavo sets up tables for a caterer on weekends . Each round table can seat 8 people . Each rectangular table can seat 10 people . One weekend , his boss asked him to set up tables for 124 people . He uses 2 more round tables than rectangular tables . Write a system of equations to find the number of round tables and rectangular tables Gustavo used . Then graph the system on a separate sheet of paper to solve the system . Let x = the number of round tables and let y = the number of rectangular tables .

(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

they charge the same amount at 20 minutes.
