Let h =  the number of horses in the field
Let c =  number of cows in the field
There are 2 more horses than cows in the field. Therefore
h = c + 2
 or
 c = h - 2               (1)
There are 15  animals in the field. Therefore
h + c = 15              (2)
Substitute (1) into (2).
h + (h - 2) = 15
2h - 2 = 15
Answer: 
The correct equation is 
2h - 2 = 15
        
                    
             
        
        
        
Answer:
triangle A
Step-by-step explanation:
the area is 16cm²
8×4/2 = 32/2 = 16
 
        
             
        
        
        
Answer:
3/16
Step-by-step explanation:
Let the size of the whole apple be T
Given that 3/4 of the apple is left, it means the size left 
= 3T/4
Since Victor plans to eat 1/4 of the pie that was left, this amounts to
1/4 * 3T/4
= 3T/16
This means that Victor will eat 3/16 of the whole pie tomorrow
 
        
             
        
        
        
Use this rule: <em>(x^a)^b = x^ab</em>
3(x + 2)^3/5 + 2 = 27
Subtract 3 from both sides
3(x + 2)^3/5 = 27 - 3
Simplify 27 - 3 to 24
3(x + 2)^3/5 = 24
Divide both sides by 3
(x + 2)^3/5 = 24/3
Simplify 24/3 to 8
(x + 2)^3/5 = 8
Take the cube root of both sides
x + 2 = 3/5√8
Invert and multiply 
x + 2 = 8^5/3
Calculate 
x + 2 = 2^5
Simplify 2^5 to 32
x + 2 = 32
Subtract 2 from both sides
x = 32 - 2
Simplify 32 - 3 to 30
<u>x = 30</u>
