<h3>Answer :</h3>
There are two statements here, showing quantities in real world which are additive inverse of each other :
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
here, we can depict going up as +2 miles and going down the trail as -2
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
Answer:
the opposite of what is in the parentheses so -(-6) would just be 6
B 3 + x is an expression because it has no =
Answer:
Infinite Solutions
Step-by-step explanation:
Distribute the 3 by multiplying it to the two terms on the right side.
5x - 6 - 2x = 3x - 6
Isolate the x value to the left and move the other terms to the right.
5x - 2x - 3x = 6 - 6
Combine all like terms.
3x - 3x = 0
0x = 0
All numbers multiplied by zero is still zero, so this equation has infinite solutions.
