Blank plus 1/2 equals 8/10​

3/10 + 1/2 = 8/10

Step-by-step explanation:

? + 1/2 = 8/10

To figure this out, you would subtract 8/10 from 1/2. But first, you want to find a common denominator.

1/2 = 5/10

8/10 - 5/10 = 3/10

3/10 can not be reduced anymore so that would be your answer.

(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
