MAVERICK [17]

Answer:

50%

Step-by-step explanation:

The P(even or divisor of 28) = P(even) + P(divisor of 28) - P(even and divisor of 28). The P(even) = 2/4 = 1/2. The P(divisor of 28) = 2/4 = 1/2. The P(even and divisor of 28) = 2/4 = 1/2 as 2,4 are even numbers and divisors of 28.

1/2 + 1/2 - 1/2 = 1/2 = 50%

A problem states: "There are 2 more horses than cows in a field. There are 15 animals in the field in all. How many horses are t
mash [69]
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
