Answer:
7/10
Step-by-step explanation:
10 marbles in a bag 7 of them are blue and the (10-7)=3 green
P( blue) = blue / total
= 7/10
Answer: the answer is x=30
Step-by-step explanation:
Standard Form looks like this:

Also, A cannot be negative and there are no fractions in Standard Form.
Now that we know the rules of Standard Form, let's get x and y on one side.
-2/3y = 2 + 8/15x
Subtract 8/15x from both sides.
-8/15x - 2/3y = 2
Multiply 2/3 by 5/5 to get a common denominator.
-8/15x - 10/15y = 2
Multiply everything by 15 to rid of the fractions.
-8x - 10y = 30
Multiply everything by -1 to make A positive.
8x + 10y = -30
8x + 10y = -30
Answer:
3x+10=(2x-17)*2
(I multiplied it by 2, since ”in circle theorems”, she angle sub tended at the center, is 2* the angle sub tended at the circumference)
3x+10=4x-34
-x = -44
x = 44
