Midpoint solve with step by step

Mathematics
1 answer:
Murrr4er [49]2 years ago
8 0

Answer:

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

Answer:

377/3

Step-by-step explanation:

In general if we have a fraction ( mixed) as ,

a\dfrac{c}{d}

Then the improper fraction will be ,

<u>Improper</u><u> fraction</u><u> </u><u>:</u><u>-</u><u> </u>

\dfrac{ d\times a + c}{d}

Using this concept we have ,

→ 125 ⅔

→ 125 × 3 + 2 / 3
