Factor by grouping. Then supply the term that is missing below. 2mn-3m+8n-12=(m+4)(?-3) The missing term ? = _____.

1 answer:

4 0

2mn - 3m + 8n - 12

Let's group the first two terms together and the last two:

2mn - 3m and 8n - 12

In the first group, m is the greatest common factor.

m(2n - 3)

In the second group, 4 is the greatest common factor.

4(2n - 3)

Therefore, (m + 4) and (2n - 3) are our factors. Our missing term is 2n.

A women made a deposit of $196.If her deposit considered of 60 bills, some of them one-dollar bills and the rest being five-doll

raketka [301]

Answer: 26 pieces of $1 bill and 34 pieces of $5 bill

Total Deposit = $196
Total Bills = 60 pieces
Value of $1 = $1
Value of $5 = $5

Lets assume all the 60 pieces were $1 bill.
The total deposit will be 60 x $1 = $60

But we know that the total deposit is $196. So the extra value must have come from the $5.

$196 - $60 = $136
There is still an outstanding amount of $136 not accounted for.

$5 - $1 = $4
The difference in the two bills is $4

Now we can find out the number of $5 bill by dividing the extra $136 by 4:
136 ÷ 4 = 34 pieces

There are 34 pieces of $5 bill.

Since there are 34 pieces of $5, the rest must be the $1 bill
60 - 34 = 26

There are 26 pieces of $1 bill.
