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

The Clark family must pay $2,820 in property tax on their home this year. The house payment $752 per month. What is their paymen
Harlamova29_29 [7]
It's actually easier than it seems. if the tax is paid in equal payments every month and the total throughout a year (12 months) is $2,820, you have to find out how much they pay every month
so divide the total by the number of months
2,820/12=235
they pay $235 in taxes every month
to find out the total of the taxes and the house payment, just add the monthly tax and the monthly house payment.
235+752
and your answer is the sum
