Answer:
3
Step-by-step explanation:
6/2=3
six halves of cookies put the halves into pairs and you get 3
(2x+5y=60)
- (2x-5y=-20)
-------------------
10y=80
y=8
2x+5(8)=60
2x+40=60
2x=20
x=10
The answer to that is (the product)
Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.
