Answer:
The meeting room must be rented for less than 7 hours
Step-by-step explanation:
There are 2 types of costs in this situation
Fixed cost = $ 33
Variable cost = 9.70t
Where t is the number of hours.
The total cost C will be the sum of the fixed cost and the variable cost
We want C to be less than 100.90
So:
We solve for t and obtain.
The dress originally costs $120.
In order to find this, you need to divide the current cost by the percentage you are paying for. Since it's 75% off, you are paying for 25% of the dress's original cost. Therefore, divide 30 by 25%.
30/.25 = $120
With what do you need help with
If 2x+2x+2x=12, then 6x=12 so x=2. x will be 2. Even in 2x-13. ;-)
The value of 2x-13 with x=2 is 4-13 = -9, but that's another question, isn't it?
The answer is
a) one solution (0,-1)
just substitute y
we are told that y = 5x-1
so do
-15x — 3 (5x-1) = 3
and solve from there
