Answer should be 4
Explanation: 30 divided by 8 = 3.75
3.75 rounded is 4
        
             
        
        
        
Basically, ur just solving for y
6x + 4y = 8...subtract 6x from both sides
4y = -6x + 8....now divide both sides by 4
y = (-6/4)x + 8/4...reduce
y = -3/2x + 2 <=== slope intercept form
        
                    
             
        
        
        
Answer:
11
<em>or</em>
2(5)+2-3
Step-by-step explanation:
if a = 5 and b=2,
you add it into the expression.
2a + b -3 --> 2(5) + 2 - 3
all you have to do is replace the letters with the (given) numbers.
then, solve.
2(5) = 10
2-3= 1
10+1 =11
the answer is 11.

Answer: 3/18 or you can simplify it to 1/6 
Step-by-step explanation: You keep 1/18 , change the division sign to multiplication  , and flip 1/3 to 3/1 so the problem goes from 
1/18 / 1/3 to 
1/18 * 3/1 = 1/6
