So, right off the bat, you can tell that the ordered pair (2,1) is most definitely NOT the solution to this system.
Answer:
8x + 8y
8 (x +y)
Step-by-step explanation:
When adding or subtracting, the terms should have exact variables like x.
3x + 5x + 8y
Here 3 and 5 have the same variable x so you can add them. (3+5=8)
8x + 8y
Now take out common number (here it's 8):
8 (x + y)
Answer:
84.3211111111/ 84.32/ 84.3
Step-by-step explanation:
In order to find range, you have to add all the numbers up and then divide by the amount of numbers that you have. So, you'd do 90.89+ 87+ 79+ 89+ 84+ 80+ 85+ 85+ 79= 758.89. Then, since you have nine numbers, you'd divide 758.89 by nine, which equals 84.3211111111, and is rounded to 84.32, or 84.3.
