Write an algebraic expression to model the unknown number situation. the sum of a number and one-third A 1-column table with 5 rows. Column 1 is labeled Addition Words with entries add, increase by, more than, sum, total. Which statements are true? Select all that apply. You can replace "a number" with a variable to represent an unknown value. You can replace "sum" with an addition sign. You can replace "sum" with an multiplication sign. You can replace "one-third" with One-third. The correct algebraic expression is One-third n

1 2 and 4

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
