Answer:
390 pens in total
Step-by-step explanation:
Each box has 6 black and 4 black
so the total amount of pens per box should be 10 because 6+4=10
Since we have to use distributive property you can write the equation (6+4)*39 because you need to figure out the total amount of pens in all the boxes.
6+4 is 10
and 10 * 39 is 390
therefore the answer is 390 pens in total
Base is 12 and height is 24
Step-by-step explanation:
Will bought several books that cost $ 2.50 each and received a $ 2 discount on the total bill. If he paid $ 10.50, how many books did he buy ?
2.50x - 2.00 = 10.50
2.50x = 10.50 + 2.00
2.50x = 12.50
x = 12.50/2.50
x = 5....he bought 5 books
Answer:
100 paws
Step-by-step explanation:
the ratio is 4:1 and you need to know is how many paws there are for 25 tails. if you divide 25 by 1 the answer is 25 and if you multiply 1 by 25 you get 25 and if you multiply 4 by 25 you get 100. (you multiply 4 by 25 because 1 was multiplied by 25 to get the amount of tails)
