Answer:
2 hours; $130
Step-by-step explanation:
We can do this by setting up an equality since we are finding when they are the same. Say x is the number of horus:
65 * x = 60 + 35* x
30 * x = 60
x = 2 hours
The cost will be the same at two hours, and plugging it in, we can get 65*2=130.
Diameter = 10.0002 inches, or 10 inches since were rounding to the nearest whole number.
Answer:
The solution is the interval (-∞,5]
Step-by-step explanation:
we have

The solution is the interval -----> (-∞,5]
All real numbers less than or equal to 5
In a number line the solution is the shaded area at left of x=5 (close circle)
