What is the value of x in this equation?

2x + 2 = -5

Decimal Form:

x=−3.5

Mixed Number Form:

x=−312

Step-by-step explanation:

Hope this helps you :)

x=-3.5

Step-by-step explanation:

you subtract the 2 from the five which will give you -7 because it's at -5 then divide by two which gives you -3.5

(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
