Anna's birthday party costs $1, plus an additional $2 for each guest she invites. Write an equation that shows the relationship between the guests x and the cost y. Write your answer as an equation with y first, followed by an equals sign.

y = $1 + $2x

Step-by-step explanation:

The one dollar represents the amount of the party alone. The two dollars multiplied by the x gets you how much money will be spent towards guests altogether. Adding these gets you the total cost. (FYI - I put the dollar sign, but you may not need it.)

6 on both sides and twelve on the top and the bottom

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
