Step-by-step explanation:
percentage of green marbles=
(total green marbles÷ total marbles )×100
1) 2x + y = 8 2) x - 3y = -3
y = -2x + 8 y = -x - 3 / -3
y-coordinate: (0, 8) x-coordinate: (-3, 0)
Because division is repeated subtraction.
For example: "10 divided by 2" means "How many times can you
subtract 2 from 10 before the 10 is all gone ?".
When you divide a whole number by ' 1 ', you're trying to find out
how many times you can subtract ' 1 ' from the whole number.
Of course, the answer is the whole number itself.
Now, when you divide a whole number by a piece less than ' 1 ',
you're trying to find out how many times you can take a piece of ' 1 '
away from the whole number. Of course THAT will be more times
than the whole number itself.
5, 10 and 8 all need to equal the same number for it to be the exact same day. 5, 10, and 8 go into 40
