It would take 6 minutes and 45 seconds
Answer:
c = $1.4
p = $2.8
Step-by-step explanation:
two equations can be derived from the question
6p + 5c = 23.80 equation 1
7p + 6c = 28 equation 2
p = plates
c - cups
multiply equation 1 by 7 and equation 2 by 6
42p + 35c = 166.60 equation 3
42p + 36c = 168 equation 4
subtract equation 3 from 4
c = 1.4
substitute for c in equation 1
6p + 5(1.4) = 23.80
p = (23.80 - 7) / 6
p = 2.8
Answer:
rate change: -8
Equation: y = 232 -8x
After 5 hours: 192
Step-by-step explanation:
8 are destroyed every hour, so there are 8 less every hour, so the rate of change is -8
It starts with 232 and loses 8 per hour, so the formula is
y = 232 - 8x
After 5 hours:
y = 232 - 8(5)
y = 232 - 40
y = 192
Answer:
x + 4/5
Step-by-step explanation:
6x - 5x + 4/5
x + 4/5
This cannot be simplified any more so that must be the answer.
