Answer 27

The total volume of this combined blackberry, blueberry and guava juice is what?
You have enough info to answer this question.

How much of this 3-juice mixture is left after the guy drinks some of it?

You might use bla to represent the amount of blackberry juice, blu to repr the amt of blueberry, and gua to represent the amt of guava juice.

Write an expression to answer this question, using either the actual measurements given, or the names bla, blu, gua.

Answer 28

This is what I wrote Initially we have blackberry and blueberry juices of 0,75L and 0.60L we have (0.75+0.60)L of juice. Since Patrick pored 0.25 L of guava juice, we have then {(0.75+0.60)+0.25}L of juice. Then he drank 0.20 L of mixture . Hence finally we have {(0.75+0.60)+0.25}- 0.20 L of juice (0.75+0.60+0.25-0.20)L=1.4L of juice
{(0.75+0.60)+0.25}- 0.20

Answer 29

Looks good. Does this approach make sense to you?

Answer 30

yes however whats Part B/

Answer 31

Part B I still kinda dont get it

Answer 32

What have you done so far on Part B? Where do you feel stuck?

Answer 33

I don't get the question.

Answer 34

There are various basic properties for simple math manipulations: addition, subtraction, associative property, distributive property, and so on.

Any idea of how to apply one or more of these properties to the problem at hand?
Which math operations did you use here?

Answer 35

I think it's associative

Answer 36

Yes. you merely add together a bunch of volumes, with the order of addition unimportant.
You could add together the first 3 numbers and then subtract the 4th from the result.
or
You could subtract the 4th number form the 3rd and then add the remaining 2 numbers. In either case the result would be the same. That's the Associative Property.

Answer 37

Yes what does it mean to "each step to simplify the expression

Answer 38

You could take my 2nd example as an example of that.

Our job is to simplify the expression bla + blu + gua - drink,
and you can combine any two terms in any order. This results in your having 3 terms instead of 4. You can combine any 2 of these 3 terms in any order. And so on.
