<span>So we want to know how many individual heels did the shoemaker bought if he bought 30 pairs of heels. So to get to the answer we must know that one pair of heels is equal to two individual heels. So now we can calculate the individual number of heels: 30 pairs * 2 = 60 individual heels. </span>
Answer:
205??????
Step-by-step explanation:
sorry if I didn't get it right
All together he made 23.40
One third of $17.55 is $5.85
When you add $17.55 and $5.85 together you get $23.40
Answer:
1st class - 22 people
coach - 57 people
Step-by-step explanation:
$85 x 22 people = $1870
$60 x 57 people = $3420
22 people + 57 people = 79 people
$1870 + $3420 = $5290
You have not given us any of the steps that Ricardo took to simplify the
expression, and you also haven't given us the list of choices that includes
the description of his mistake, so you're batting O for two so far.
Other than those minor details, the question is intriguing, and it certainly
draws me in.
If Ricardo made a mistake in simplifying that expression, I'm going to say that
it was most likely in the process of removing the parentheses in the middle.
Now you understand that this is all guess-work, because of all the stuff that you
left out when you copied the question, but I think he probably forgot that the 3x
operates on everything inside the parentheses.
He probably wrote that 3x (x-3) is
either 3x² - 3
or x - 9x .
In reality, when properly simplified,
3x (x - 3) = 3x² - 9x .
