An exam will have 20 questions worth a total of 100 points. There will be true-false questions worth 3 points each and short answer worth 11
points each. The students want to know how many of each type there
will be on the test. The teacher won't tell. How many short answer
questions are there?

if you need just tell me and i will come to the rescue.

step-by-step explanation:

the answer is ! ?

(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

if you was gonna solve for a, a is a   < -12
