The answer to your question is, The pool dropped 1.38/16 inches per hour.
Answer:
The number of pounds of:
Decaffeinated coffee = x = 5 pounds
Regular coffee = y = 9 pounds
Step-by-step explanation:
A 14 -pound mixture of coffee that contains both decaffeinated and regular coffee costs $37. The decaffeinated coffee costs $2 per pound, and the regular coffee costs $3 per pound.
Let the number of pounds of:
Decaffeinated coffee = x
Regular coffee = y
Hence, our system of equations =
x + y = 14..... Equation
x = 14 - y
2x + 3y = 37....... Equation 2
We substitute 14 - y for x in Equation 2
= 2(14 - y) + 3y = 37
= 28 - 2y + 3y = 37
= - 2y + 3y = 37 - 28
= y = 9 pounds
Solving for x
x = 14 - y
x = 14 - 9
x = 5 pounds
Therefore,
The number of pounds of:
Decaffeinated coffee = x = 5 pounds
Regular coffee = y = 9 pounds

Step-by-step explanation:
Answer:
c = -10
Step-by-step explanation:
16c -24=4c -144
Subtract 4c from both sides
16c - 4c - 24 = 4c - 4c - 144
12c - 24 = -144
Add 24 to both sides
12c -24 + 24 = -144 + 24
12c = -120
Note: -144 + 24 = -120
12c = -120
Divide both sides by 12
12c/12 = -120/12
c = -10
Note: 12/12 = 1 and -120/12 = -10
Checking :
16c -24=4c -144
Put c = -10
16(-10) - 24 = 4(-10) - 144
-160 - 24 = -40 - 144
-184 = -184
Therefore
c = -10
