You can add like terms. Like terms are terms that have the same variables and the same exponent.
11x + 5 + -11x + 29 =
= 11x + -11x + 5 + 29
= 34
Answer: 34
The answer is the mean is 8. The range is equal to the largest number, 10 minus the smallest number, 5. It equals 5, so d is wrong. The mean is all of the values added together, 80, divided by the number of values, 10. So, 8. The median is the middle which is between 7 and 8, so 7.5. Five has no dots.
Answer:
- 1700: $50
- 2000: $60
- 7000: $90
Step-by-step explanation:
You can read the answers from the graph. Find the usage on the horizontal scale, and look at the vertical scale to find the corresponding charge.
__
<h3>1700 gallons</h3>
The value 1700 is between 1000 and 2000, so will be between 1 and 2 on the horizontal scale. The graph is flat in that region. The charge is $50.
__
<h3>2000 gallons</h3>
The graph has a jump at 2 on the horizontal scale. The solid dot tells you that the charge is $60.
__
<h3>7000 gallons</h3>
At 7 on the horizontal scale, the graph is increasing from 80 to 100. At 7000 gallons, the line passes through the grid intersection indicating the charge is $90.
