8h+(-6.3d)-15+4d-3.3h
Drupady [299]

Answer:

Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.

Here is the simplified version:

−2.3d + 4.7h − 15

Step-by-step explanation:

Combine Like Terms:

=8h+−6.3d+−15+4d+−3.3h

= (−6.3d+4d) + (8h+−3.3h) + (−15)

= −2.3d+ 4.7h − 15

Help plz? i don’t understand the example
nataly862011 [7]

Answer:

The example is telling you to first add up each number then divide by the amount of numbers that are present in the set. There are four in this example.

Secondly the difference between each data point will differ from each number. Basically subtract the sum from each number. Which is 5 in this case. But if its negative flip it to a positive.

Then add up each absolute value and divide by 4 twice.

Hi there, so we know that all triangles add up to 180 degrees so we will take 38 and add it with 25 to get 63 then we subtract 180 by 63 to get 117 which is your awnser!! I mean I might be wrong but I’m probably right. I hope this helps!! Have a great morning, night, or day, Whatever it is for you!
