:D.
Step-by-step explanation:
7/22*6/21=42/462=.09=9% chance of a yellow then a yellow selection.
2/22*17/21=34/462=.0736=7.36% chance of green & then not a blue.

Hey there Bfarrar07 !
This is pretty simple when you think about it.
With algebra problems like this, you want to set it equal to zero.
So your first step is to take 35x + 10 and set it equal to zero.
35x + 10 = 0
Then bring the 10 to the other side by subtracting it, so you have something like this:
35x + 10 (-10) = -10 (Remember, what you do to one side you have to do to the other!) So when you take 10 from the left, you have to take ten from the right.
You now have 35x = -10
In order to get x by itself, you need to divide the problem by 35.
35x/35 = -10/35
On the left hand side, the 35's cancel out, so you're left with x.
And on the right hand side you have -10/35
So x = -10/35 (Don't forget to simplify!)
-10/35 can be reduced to -5/7
X = - 5/7
Hope this helps!
Given:
The base of 40-foot ladder is 8 feet from the wall.
To find:
How high is the ladder on the wall (round to the nearest foot).
Solution:
Ladder makes a right angle triangle with wall and ground.
We have,
Length of ladder (hypotenuse)= 40 foot
Base = 8 foot
We need to find the perpendicular to get the height of the ladder on the wall.
Let h be the height of the ladder on the wall.
According to the Pythagoras theorem,
Taking square root on both sides.
Height cannot be negative. Round to the nearest foot.
Therefore, the height of the ladder on the wall is 39 foot.
6 / 9 = 2/3 ( since dividing top and bottom be 3 gives 2/3)
Also 4/6 = 2/3
