1. Two of the radii for the circumscribed circle below have the expression 3x-2 and 4x -8. What is the length of the radius of the circle?

9514 1404 393

  16

Step-by-step explanation:

Radii of the same circle are the same, so we have ...

  3x -2 = 4x -8

  6 = x . . . . . add 8-3x

  3x -2 = 3(6) -2 = 16 . . . . the radius of the circle

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
