Answer: 3x-5y=-9 is simplified to y=3/5x+9/5
x+2y=8 is simplified to y=-1/2x+4
The volume of the triangluar block is 4 cubic inches. What is the approximate length of y? -- 2.8 inches
Hey there!
If we have two white marbles and seven purple marbles, our first probability is out of nine.
First of all, we have the probability of selecting a purple marble, 7/9.
Now, if we do not replace it, there are only eight marbles left. Therefore, getting a white marble is 2/8, or 1/4.
We multiply these probabilities together to get our answer to a.
7/9(1/4)= 7/36
a. 7/36
Now, let's do b. We have 2/9, and then 1/8, giving us 1/36.
b. 1/36
Now, let's calculate selecting two purple to help us with C.
We have 7/9, and then 6/8, or 3/4.
7/9(3/4)= 7/12
Since there is a majority of purple marbles, there is a C) greater probability of selecting two purple marbles in a row.
I hope this helps!
To find equivalent equations, you simply have to simplify both of these :)
a) 5/6(x - 6) + 1/6(3 - x)
Simplify.
5/6x - 5 + 1/2 - 1/6x
Add like terms.
(5/6x - 1/6x) + (-5 + 1/2)
Simplify.
4/6x +(-4.5)
Simplify.
2/3x - 4.5
b) (y + 7)4 + 8 - 5y
Simplify.
4y + 28 + 8 - 5y
Add like terms.
(4y - 5y) + (28 + 8)
Simplify.
-y + 36
~Hope I helped!~
