Please HELP im posting a lot but the points will go up!

5.6

Step-by-step explanation:

Intersecting Chords Formula:

(segment piece) x (segment piece) =  (segment piece) x (segment piece)

3.2 * x= 4.8 * 1.6  

Divide each side by 3.2

x =7.68/3.2

x=2.4

We want to find AC

AC = 3.2 +x

AC = 3.2+2.4

AC =5.6

d

step-by-step explanation:

d

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
