Answer:
1 3/4
Step-by-step explanation:
You can set it up like the distrubtive property first
3/4(2+ 1/3)    Next you use the distirbutive property instead of adding inside the parenthesis and you multiply the 3/4 by 2 and then the 3/4 by 1/3
Use 2 as 2/1 in fraction problems
3/4 * 2/1        Now multiply the numerators together and the denomenators together
3 * 2 = 6          4 * 1 =4
6/4
3/4 *1/3 
3 * 1 =3
4 * 3 =12
3/12
Now we have to make them both like terms (same denominator) so we can add them, we will multiply the 6/4 by 3 (Both top and bottom)
6 * 3 = 18               4 *3 =12
18/12
 
Now we add the fractions
3/12 +18/12 = 21/12
Reduce that and you get 
21/12 = 1 9/12  or 1 3/4

Answer:
-6x+5y+8
Step-by-step explanation: subtract 9xfrom 3x
Subtract 2 from 10
-6x+5y+10-2
-6x+5y+8
 
        
             
        
        
        
Slope of  2y = x + 5:-
This is y = 0.5 x + 2.5  in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
