Answer:
-2
Step-by-step explanation:
Answer:
Letting x represent the number of signatures
then
520 + 6x = 1000
Answer: Undefined
Step-by-step explanation:
4y+x=12, 2x=24-8y
Isolate x by subtracting 4y
4y+x=12
x=12-4y
Plug the equation for x in to anywhere you see the variable x in the other equation
2(12-4y)=24-8y
Distribute 2
24-8y=24-8y
Get the variables on one side so add 8y (cancels out)
24=24
Can’t solve its undefined
The associative property states a + (b + c) = (a + b) + c
So your answer is associative property.
Your answer is 0, use PEMDAS and left to right 1+1=2 then subtract your 2, so 2-2=0
