Answer:
x/i=22
Step-by-step explanation:
x/33=2/3*i
*33       *33
x=2/3*33*i
/i              /i
x/i=2/3*33
x/i=22
 
        
             
        
        
        
3(v + 2) + 4 = 13
Mutiply the bracket by 3 
(3)(v)= 3v 
(3)(2)= 6 
3v+6+4= 13 
3v+10=13 
Move +10 to the other side 
Sign changes from +10 to -10
3v+10-10= 13-10
3v= 13-10
3v= 3 
divide both sides by 3 
3v/3= 3/3
v= 1
Answer : v= 1

Answer:
64 teachers
Step-by-step explanation:
We can use ratios to solve
14 students   896 students
----------------- = -------------
1 teacher          x teachers
Using cross products
14 * x = 896*1
Divide each side by 14
14x/14 = 896/14
x =64
