At the movie theater chid admission is 5.70 and adult admission is 9.90 on Sunday 154 tickets were sold for a total sales price of 1125.60 how many child tickets were sold that day

94 Child tickets were sold.

Step-by-step explanation:

Let x represent child tickets

Let y represent adult tickets

Cost Equation: 5.70x + 9.75y = 1306.10

Quantity Equation: x + y = 173

Multiply the Quantity Equation by -5.70

     5.70x + 9.75y = 1306.10

   -5.70x  - 5.70y = -986.10

                   4.05y = 320.00

                 ÷4.05   ÷4.05    

                          y =   79

x +  y  = 173

x + 79 = 173

x         = 94

(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
