Answer:
carlos served 16 times dan served 64 times and karen served 9 times
Step-by-step explanation:
im just going to say 16 + 64 + 9 = 89
Answer:
Carlos = 16
Dan = 64
Karen = 9
Step-by-step explanation:
Let Carlos be x
Dan = 4x
Karen = x - 7
Their total is 89
Create an equation of Carlos + Dan + Karen = 89
x + 4x + x - 7 = 89
Combine like terms
6x - 7 = 89
Add 7 on both sides to get rid of 7
6x = 96
Isolate x by dividing by 6 on both sides
x = 16
Substitute the amount of orders each person served
Carlos = 16
Dan = 64
Karen = 9
Hope this helps :)
Have a great day!

k = - 9
Step-by-step explanation:
h(x) = x² + 3
g(x) = x² - 6
g(x) = h(x) + k
x² - 6 = x² + 3 + k
-6 - 3 = k
k = - 9
