Need quickly (: a grocer sells 30 loaves of bread a day. the cost is $2.50 per loaf. the grocer estimates that for each $0.50 increase in cost, 2 fewer loaves of bread will be sold per day. let x represent the number of $0.50 increases in the cost of a loaf of bread. for what number of $0.50 increases in the cost of a loaf of bread will the grocer's generated revenue be greater than zero?

(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
