23 + 8m + 4n - 5m - 27​
mylen [45]

Answer:

-4 + 3m + 4n

Step-by-step explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

<u>So we should start on the number without variables:</u>

23 and 27

<u>Match them up together and you should find your first equation:</u>

23 - 7

==> -4

So we should have  -4  +  8m  +  4n  -  5m

Now we should combine the numbers with the variable of m:

8m and 5m

<u>Match them up together and you should find your first equation:</u>

<u></u>

8m - 5m

==> 3m

So we should now have -4  + 3m  + 4n

<u></u>

<u>Since there are no other variables of n, we are all done:</u>

<u>-4  + 3m  + 4n  is  your  final  answer </u>

Ava is in charge of bringing bottled water to a party that has 42 guests.
olya-2409 [2.1K]

Answer:

a - about 3 packs cause you have to round up

b - $50.76

Step-by-step explanation:

First you divide 42 and 18.

42/18=2.33

You have to round up cause you can't have half of a pack, you can't just buy half of a pack.

So, it is rounded to 3 packs.

Next you have to multiply the number of packs and the cost of each pack of water bottles.

16.92*3=$50.76

a - you have to buy 3 packs

b - the total cost is $50.76
