Answer:
NOTE: Standard form is Ax+By=C
Distribute -1
5a -a +3b
Rewrite
5a +3b = -a
Multiply every term by -1 so -a will be positive
-5a -3b = a
Answer:
Using the formula
C=2πr
Solving for r
r=C
2π=35
2·π≈5.57042

Answer:
1/7
Step-by-step explanation:
The bag contains 2 red balls, 3 blue balls and 10 green balls.
The total number of balls in the bag is:
2 + 3 + 10 = 15 balls
The probability of picking a green ball is:
10/15 = 2/3
There are now 14 balls left in the bag.
The probability of picking a blue ball is:
3/14
Therefore, the probability of picking a green ball and a blue ball is:
2/3 * 3/14 = 2/14 = 1/7
It's just like counting up
So how its 5, 6, 7
it would be 1.5, 1.6, 1.7
