The vega family has a cell phone plan that costs 75 per month incluiding taxes and fees. the plan lets the 5 members of the vega family share 1,000 minutes of talk time per month and 400 text messages per month. any minutes over 1,000 cost 1 per minute, and any texts over 400 cost 2 per text.
because of a family emergency, the family uses 1,050 minutes and 415 texts in march. write an expression you could use to find the amount of the vega's cell phone bill for march. evaluate the expression show your work

(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
