Will give brainlest Which answer choice correctly represents an algebraic expression for the
sum of 15 and a number?
OA) 15n
OB) 15 - n
OC) 15 + n
OD) 15/n

Option C (15 + n)

Step-by-step explanation:

The phrase "the sum of" indicates addition.

This means we would write the sum of 15 and a number as 15 + n, where 'n' is the unknown value.

Option C should be the correct answer.

Hope this helps.

(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
