Solve the following addition and subtraction problems. a. 90 cg 95 mg + 7g 12 cg 18 mg b. 4 kg 2hg + 14 kg + 5 kg 17 hg c. 12 dag 5 g – 7 g d. 8 kg – 9 hg

The answers are:

a. 8,133mg

b. 24.9kg

c. 108g

d. 7.1 kg

First, we need to convert all the units for each option, in order to be able to do the addition and substractions, so:

For a.

So,

For b.

So,

For c.

Let's assume the missing signs as negative signs

so,

For d.

Let's assume the missing signs as negative signs

So,

Have a nice day!

i do not know the answer i am sorry

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
