1. Expand by distributing terms.
5x times 3 + 5x times -7y
2. Simplify 5x times 3 to 15x.
15x + 5x times -7y
3. Simplify 5x times -7y to -35xy.
15x - 35xy
Then you’re done. Hopefully this helps.
12-4=8 which means 12-8=4 which means now you have the difference of 4 and 8+4=12 which means now you have the sum of 12
The total number of marbles is

.
If we draw a red marble, the chance of that occurring is

.
Now the total number of marbles left is 7. If we then draw a green marble, the chance of that occurring is

.
So the chance of drawing a red, then green, marble is

.
