2 2/3 = 2x3+2/3 = 8/3
8/3 / 1/3 = 8/3 x 3/1 = 8/1 = 8
        
                    
             
        
        
        
Answer:
C. x=8.5
Step-by-step explanation:
-18+3x+x=-2(2x-25)
-18+4x=-4x+50
    +4x   +4x
-18+8x=50
+18      +18
8x=68
8    8
x=8.5
 
        
             
        
        
        
The equivalent expression is 10x+5y-15z
        
                    
             
        
        
        
Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
 
        
             
        
        
        
Answer:
x = 5
Step-by-step explanation:
Locate - 3 on the y- axis, move across to the right to where the graph is.
Go vertically up from this point to meet the x- axis at point x = 5
Thus
f(x) = - 3 ⇒ x = 5
