Solve for the value of x a- 6 b- 16 c- 100 d- 12

these two angles are supplementary interior angles

therefore they add up to 180

16x+4 + 80 = 180

combine like terms

16x+84 = 180

16x = 96

divide each side by 16

x = 96/16

x = 6

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
