Because you have to go in the order of PEMDAS, parenthesis, exponents, multiplication, division, addition, and subtraction. From what you are saying, 'why you must simplify 3 to the second power first' it seems that you have no parenthesis, so you move onto what is next, which is exponents, in this case, 3 to the power of two.
1/3 Probability both are red
red picked first:
6/10
red picked second:
5/9 (9 as first red marble not replaced so 5 red marbles remaining and 4 blue marbles still)
6/10 * 5/10 = 1/3
Hope that helps!!
Answer:
Step-by-step explanation:
We need to write this equation in y=mx+b where m is the slope.
3y= -2x +9
y= -2/3 +9
So now that it is in the form of y=mx+b, we can find the slope. -2/3 is the slope of the equation. Hope that helps!
Answer:
28/3
Step-by-step explanation:
2 1/3 divided by 1/4
We’ll start by 2 1/3
Multiply 3 x 2 and then add 1
3 x 2 = 6 + 1 = 7
Then add the denominator back
7/3
Now divide 7/3 by 1/4 like this!
Start by multiplying 4 by 7
4 x 7 = 28
Then multiply 3 by 1
3 x 1 = 3
Final results: 28/3
