Barkley's team won 40% of their games last season. If they won 12 games total last season, how many games did they play?

30 games

Step-by-step explanation:

if they won 12 games which is 40% of their total games played 100% is the number of games played .form an equation...  

if 12=40

   x=100      cross multiply 12 and 100 then divide by 40 to get x

12×100=1200÷40=30.

so, converting firstly the mixed fractions to improper fractions and then "adding".

(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
