Answer:
The cow has a greater heart rate than the horse.
Step-by-step explanation:
The question demand we calculate the heart beat of each animal in relation to time . The number of heart beat per unit time can be computed as follows .
The horse heart rate is 440 heart beat in 10 minutes . The heart rate can be simplified as
Rate = 440/10
Rate = 44 heart beat per minute
The cow heart rate can be simplified as
Rate = 390/6
Rate = 65 heart beat per minute
From the Heart rate calculated above the cow has a higher heart rate than the horse.

Answer: 12 houses are left to be sold.
Step-by-step explanation: The starting number is 80 units of houses. Last month, 2/5 of them were sold which means, houses sold last month were
Houses sold = 2/5 x 80
Houses sold = 32
If 32 houses were sold, then the houses left over were 80 - 32 which equals 48.
This month, 3/4 of the remaining houses were sold which means 3/4 of 48 houses.
Houses sold = 3/4 x 48
Houses sold = 36
If out of the remainder of 48 houses, 36 were sold, then houses left over would be
Left over = 48 - 36
Left over = 12.
Finally, there were 12 houses left to be sold

Answer:
-4
Step-by-step explanation:
18x - 9(x - 1) = 5(3x + 3)
Step 1: Distribute
18x - 9x - 9 = 15x + 15
Step 2: Combine like terms
9x - 9 = 15x + 15
Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side
9x - 9 = 15x + 15
-9x -9x
-9 = 6x + 15
-15 -15
-24 = 6x
/6 /6
-4 = x
