If there are x $13 each books and y $17 each books, then we can build the following equations:
x + y = 8 (or y = 8 - x)
13x + 17y = 128 (or y = 128/17 - 13x/17)

Answer: 33 cookies.
Step-by-step explanation: To find the 75% of 44 cookies, use these steps:
Step 1: Our output value is 44.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 44 = 100%.
Step 4: Similarly, x = 75%.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right-hand side) of both equations have the same unit (%); we have:
= 
Step 7: Again, the reciprocal of both sides gives:
= 
Therefore, 75% of 44 is 33. Thus, it is 33 cookies.
The number of minutes remaining in the poultry's temperature zone is; 3 hours and 45 minutes
<h3>How to find the temperature zone?</h3>
We are told that On the counter is poultry that has been left at a temperature of 17.5 °C for 15 minutes.
Converting 17.5°C into Fahrenheit equals 63.5 °F. This temperature in degrees Fahrenheit is within the danger zone. Now, hot food can be held in the danger zone for 4 hours. Due to the fact that the food has been on the counter for 15 minutes already, it means that it can be held on the counter for another 3 hours and 45 minutes before it becomes unsafe.

Answer:
a = 9, b = 3, c = 0
Step-by-step explanation:
f(x) = (1/3)^x
a = f(-2) = (1/3)^-2= 9
b = f(-1) = (1/3)^-1 = 3
c = f(0) = (1/3)^0 = 1
whenever something is to the power of 0, the answer will always be 1
