Answer:
Question 1:  4/5 or %80
Question 2:  7/10 or %70
Step-by-step explanation:
<u>Step 1:  Find the total amount of marbles</u>
5 + 2 + 3
<em>10</em>
<em />
<u>Step 2:  Find the probability of not drawing a black marble</u>
Add the total amount of marbles that are not black
5 + 3
<em>8</em>
<em />
Now find the probability:  
8/10
4/5 or %80
Answer:  4/5 or %80
<u>Step 3:  Find the probability of not drawing a red marble</u>
Add the total amount of marbles that are not red
5 + 2
<em>7</em>
<em />
Now find the probability:
7/10 or %70

Answer:
1cm=5ft
Step-by-step explanation:
divide 15 by three
 
        
             
        
        
        
The graph of y=tanx+1 crosses the y-axis at (0,1).
        
             
        
        
        
2x^2=4x
I'm pretty sure this is it because there are only 2 like terms so you can't combine anything with 4x.
