You have a probability of 7% to pick out the first orange marble then you have a probability of 8% to pick out the second orange.
For the second question (5/6)/(4) is the same as (5/6)*(1/4) so just multiply across and you get (5/24)
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
The surface area is 54 square inches

We have:

We know. The line <em>l</em> passes throught the point (9, -7). Substitute the coordinates of the poin to the equation of line<em> l </em>:
