Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7
Step-by-step explanation:
The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.
The answer is -5
Explanation: Divide 2 to get rid of the top number. It looks like this
-10. 2y
___. ___
2. 2
What this does is remove the two from the Y and sets it by itself. Then you divide the -10, and the answer is -5
A: (450>/10)+5
B: 44 Students

Average weight is when you add up all the weight and divide by the number of objects
if you count the number of x's you will see that you have 10 sandwiches
now add up all the weight
1/8 +1/8+ 1/4+1/4+1/4+1/4+ 3/8+ ....
once you have total weight, divide that number by 10
