Answer:
30 red marbles
Step-by-step explanation:
If the ratio is 2 red marbles for every 5 blue marbles then you would add them together to find out how many marbles are in one group.
2+5=7
There are 7 marbles in each group.
Now we have to find out how many total groups there are by dividing the total amount of marbles by the amount in each group.
105÷7=15
There are 15 groups of 7 marbles.
Looking back at the ratio, we know that the 15 groups each have 2 red marbles and 5 blue marbles. So if there is 2 red marbles 15 times (2 marbles in 15 groups) we would multiply.
2×15=30
There are 30 red marbles.
I hope that makes sense.
You would add 6+3 which equals 9 and then you would divide 111/9 and you get 12.33333...
So he bought 12 books
Well if he puts 6 on each of the 5 notebooks, you'd do 5*6 and get 30. If 10 are on each sheet you'd do 30/10 & end up with 3 sheets of stickers :)
Definitely B. Note how the powers of y are presented in descending order by power: y^8, y^7, y^1.
