The hardware store sells red buckets, which hold 4 liters of water, and green buckets, which hold 3 liters. Roxanne bought 7 buckets. Her buckets will hold 24 liters in total. How many of each type of bucket did Roxanne buy?

3 red buckets and 4 green buckets

Step-by-step explanation:

You make two equations, one that shows the number of buckets and one that shows the number of liters. We'll make x = the red buckets and y = the green buckets.

x + y = 7 --> This is our first equation, it shows us that x number of red buckets + y number of green buckets equal 7 total (since Roxanne bought 7 buckets).

4x + 3y = 24 --> This is our second equation, it shows us that 4 liters of x number of red buckets + 3 liters of y number of green buckets equals 24 liters total (since her buckets will hold 24 liters in total)

Now that you have identified the two equations, you can solve for variable in equation one, then plug the new equation into equation 2:

x + y = 7 --> y = 7 - x <-- PLUG THIS into the y value of 4x + 3y = 24

4x + 3(7 - x) = 24 <-- SOLVE --> x = 3 <-- NOW WE KNOW THAT THERE ARE 3 RED BUCKETS

plug 3 in for x in the first equation --> 3 + y = 7 --> y = 4

So now we know that there are 3 red buckets, and 4 green buckets.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
