Midpoint solve with step by step

Step-by-step explanation:

If D is the midpoint of CE, that means that D is exactly in the middle of CE, splitting it in 2 equal length segments.  That means that CD = DE in length.  If CD = 9x - 7 and DE = 3x + 17, then

9x - 7 = 3x + 17 and

6x = 24 so

x = 4

Now we'll sub 4 in for x in either expression for half the length.  If DE = 3x + 17, then when we sub in 4 for x: 3(4) + 17 = 29.  That means that half the length of CE is 29.  Double that and you'll get that the length of CE = 58

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

i think it might be a but you might want a second opinion
