Answer with Step-by-step explanation:
We are given a variable b
We have to state the additive property of zero using the variable b.
Additive property of zero: It states that when any number b is added to zero then we get sum is equal to number itself.
Mathematical representation:
Suppose, a number b=9
Then, 9+0=9
0+9=9
This property is called additive property of zero because when 9 is added to 0 then we get sum equals to 9.
Answer:
The overall change is -250 feet. 50 times 5 is 250 feet, and the mountain climber descended. Therefore, the change is -250 feet in elevation.
Step-by-step explanation:
Answer:
the overall changes is -250 its descended 50×5=250
Step-by-step explanation:
Answer:
∴ K = 0
Step-by-step explanation:
- K -17 = -5 - K -12
- K + K = - 5 - 12 + 17
0 K = -5 + 5
0 K = 0
∴ K = 0
Answer:
All real numbers are solutions.
Step-by-step explanation:
−k−17=−5−k−12
−k+−17=−5+−k+−12
−k−17=(−k)+(−5+−12)
−k−17=−k+−17
−k−17=−k−17
−k−17+k=−k−17+k
−17=−17
−17+17=−17+17
0=0
