Nicole has nine dollars to spend on cards she finds friends with the same amount of money to split the cost of a set once it cos
anyanavicka [17]

Answer:

Each Friend will get \frac{x}{3} cards.

Step-by-step explanation:

Let the number of cards be x.

Given:

Amount Nicole used to spend on cards = $9

Total cost of one set =$27

Also, she finds friends with the same amount of money to split the cost of a set.

So, Number of friends she finds can be calculated by dividing the Cost of 1 set  with amount of money Nichole used to spend on cards.

Number of friends she finds = \frac{27}{9} = 3

Hence she finds 2 friends and 1 is nichole hence there are 3 persons carrying $9 to buy $27 set of card

Now, Number of cards each friend gets is equal to Total number of Cards in 1 set divided by number of people.

Number of cards each friend = \frac{x}{3}

Hence Each Friend will get \frac{x}{3} cards.

Answer:

a. m = Vd

b. 6.012g

Step-by-step explanation:

a.  you need to rearrange the equation so that you're solving for m. you can do so by multiplying both sides by V so you end up with

Vd = m or m = Vd (i prefer writing it this was purely cause it looks better)

b. now, you can plug in each value into the new equation so you get

5.01g/cm3 x 1.2 cm3 = m

from here you just multiply as normal

Find the least common denominator for these two rational expressions. x/x^2-25, c/x^2-3x-10
34kurt

Answer:

Step-by-step explanation:

Hello,

Let 's notice that

x^2-25=x^2-5^2=(x-5)(x+5) \ \ and \\\\x^2-3x-10=(x-5)(x+2) \ \text{as sum of the zeroes is 3 and the product is -10}

So the least common denominator is

(x-5)(x+5)(x+2)

hope this helps

Answer:

Your answer of coplanar is correct

Step-by-step explanation:

A skew line are 2 lines that aren't parallel and do not intersect.

Since there are arrows on either end of AC and RS , it mean those lines continue, and they will eventually intersect.

It is also not the other 2 clearly, since they do intersect and they don't make a 90° angle

So yes,

The answer is Coplanar

Hope this helps.
