7, 9, 10, 12, 14, 16, 17
You can find that the range is ten by subtracting the largest number (17) by the smallest number (7) which leaves you with 10. You can find the mean by crossing off a number from each side, one at a time, until you land on the middle which is 12. I hope this helps, let me know if you have any questions!
Answer:
Step-by-step explanation:
x^2 + 17x + 60
(x + 12)(x + 5)
Answer:
Option A) Combined, with a saving of x-y cents
Step-by-step explanation:
We are given the following in the question:
The rate to mail a package is x cents for first pound and y cents for each additional pound.
Weights of packages =
3 pounds and 5 pounds
Cost of combined package:
Total weight = 8 pounds
Cost of sending separately:
Difference between cost of sending the packages separately and combined
Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents
Thus, the correct answer is:
Option A) Combined, with a saving of (x-y) cents
Answer:
5
Step-by-step explanation:
this can be solved using simultaneous equation
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
The answer would be 3.3944867e+29 but seeing how you didn’t give more detailing I’m not sure if it’s specifically the answer you need.
