The coefficients are 7, 3, and 5. Coefficient just means the number before the variable
300 divided by 15 is 20 so 20 times 15 is 300

Answer:
11 and 3
Explanation:
11 + 3 = 14
14 / 2 = 7
Mean = 7
11 - 3 = 8
Range = 8
Answer:
The solution is (3, -3)
Step-by-step explanation:
5x + 2y = 9
2x - 3y = 15
Use elimination by addition/subtraction. Multiply the first equation by 3 and the second by 2, obtaining:
15x + 6y = 27
4x - 6y = 30
----------------------
19x = 57
This yields x = 3.
Substituting 3 for x into 5x + 2y = 9, we get 5(3) + 2y = 9, or
15 + 2y = 9, or
2y = -6
This yields y = -3.
The solution is (3, -3)
