If 45 cookies will serve 1 person how many cookies are needed for 30 students.

I have no idea how this question came up but the answer is 1,350.

Step-by-step explanation:

Simply, if one person gets 45 cookies (okay same) and we have 30 students that want to be served the same amount, then the equation is 45 times 30, which can easily be put in a calculator. boom, 1350

ab will be equal to

(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
