Multiply using distributive property: -5 ( 10 + 3y ) =

-50 - 15y

Step-by-step explanation:

-5 ( 10 + 3y )

First distribute the -5 by multiplying it by 10 and 3y

(-5 x 10) + (-5 x 3y)

Than simplify

(-50) + (-15y)

Adding a negative is like subtracting a positive so you can turn (-50 + -15y) into (-50 - 15y)

Than you have your answer

-50 - 15y

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
