Problem 10 :
A football team loses 3.5 yards on their first play. On the next play, they gain 3.5 yards. What is the overall increase or decrease in yards ?
Problem 1 :
Find the additive inverse of '-15'.
Solution :
The given number is a negative number.
Then, its additive inverse is the number itself with positive sign.
So, additive inverse of '-15' is
+15
Problem 2 :
Find the additive inverse of '-0.3'.
Solution :
The given number is a negative number.
Then, its additive inverse is the number itself with positive sign.
So, additive inverse of '-0.3' is
+0.3
Problem 3 :
Find the additive inverse of '3'.
Solution :
The given number is a positive number.
Then, its additive inverse is the number itself with negative sign.
So, additive inverse of '3' is
-3
Problem 4 :
Find the additive inverse of '1/7'.
Solution :
The given number is a positive number.
Then, its additive inverse is the number itself with negative sign.
So, additive inverse of '1/7' is
-1/7
Problem 5 :
Simplify :
(-9) + 9
Solution :
The numerical expression '(-9) + 9' is the sum of '-9' and its additive inverse '+9'.
We know the fact that the sum of a number and its additive inverse is zero.
So,
(-9) + 9 = 0
Problem 6 :
Simplify :
7 + (-7)
Solution :
The numerical expression '7 + (-7)' is the sum of '7' and its additive inverse '-7'.
We know the fact that the sum of a number and its additive inverse is zero.
So,
7 + (-7) = 0
Problem 7 :
Given :
5 + x = 0
Find the value of 'x'.
Solution :
It is given that the sum of '5' and 'x' is zero.
Then, additive inverse of '5' is 'x'.
But, additive inverse of '5' is '-5'
So,
x = -5
Problem 8 :
Given :
(-7/8) + (x/8) = 0
Find the value of 'x'.
Solution :
It is given that the sum of '-7/8' and 'x/8' is zero.
Then, additive inverse of '-7/8' is 'x/8'.
But, additive inverse of '-7/8' is '7/8'
So,
x/8 = 7/8
x = 7
Problem 9 :
Given :
(2/3) + (x/6) = 0
Find the value of 'x'.
Solution :
It is given that the sum of '2/3' and 'x/6' is zero.
Then, additive inverse of '2/3' is 'x/6'.
But, additive inverse of '2/3' is '-2/3'
So,
x/6 = -2/3
Multiply each side by 6.
x = -4
Problem 10 :
A football team loses 3.5 yards on their first play. On the next play, they gain 3.5 yards. What is the overall increase or decrease in yards?
Solution :
Step 1 :
Use a positive number to represent the gain in yards and a negative number to represent the loss in yards.
Step 2 :
Find -3.5 + 3.5.
Step 3 :
Start at -3.5.
Step 4 :
Move | 3.5 | = 3.5 units to the right, because the second addend is positive.
The result is 0.
This means the overall change is 0 yards.
