Megan buys 3 bracelets and 3 necklaces each bracelet cost 5 dollars each in dollars of one she gave the clerk 40$
Tatiana [17]

Not sure what answer your needing so here is a breakdown of the amounts.

3 bracelets times $5 equals $15

How much is each necklace?

Subtract $15 from $40 you have $25 left. Then you divide $25 by 3 you get each necklace costs $8.33 so three necklaces cost $24.99

When you add $15 from the bracelets and $24.99 from the necklaces your total is $39.99 that’s why Megan gave the clerk $40

Hope this helps

Find the difference <br> 5 2/3 - 3 1/5 <br> A. 5 2/3<br> B. 8 13/15<br> C. 2 7/15<br> D. 3 1/5
RSB [31]

To find the difference of given expression:

5\frac{2}{3} -3\frac{1}{5}

First step is to subtract the whole number5 and 3.

So, 5 - 3 = 2.

Now we can find the difference of fractions.

To subtract the fractions , we need to find the common denominator.

Common denominator of 3 and 5 is 15.

So, we need to make both the denominator equal to 15.

\frac{2}{3} =\frac{2*5}{3*5} =\frac{10}{15}

Similarly, \frac{1}{5} =\frac{1*3}{3*5} = \frac{3}{15}

Therefore, \frac{2}{3} -\frac{1}{5} =\frac{10}{15} -\frac{3}{15}

=\frac{10-3}{15}

= \frac{7}{15}

So, the difference of given expression is 2\frac{7}{15}.

So, the correct choice is C.

18 meters by 14 meters

Step-by-step explanation:

18 meters by 14 meters

Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).

This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:

2L+2W = 64

Now we know the area enclosed must be 252 so we have:

L* W = 252

Rewriting the second equation we get:

Plug this into first equation to get:

(multiply everything by L)

Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.

Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).
