Answer:
(a) [tex]+15[/tex]
(b) [tex]+55[/tex]
(c) [tex]-10[/tex]
(d) [tex]-\$2,000[/tex]
Step-by-step explanation:
We are asked to read the given real-world description. We are asked to write the integer that represents the opposite of the opposite for given description.
We know that opposite of a number is negative of that number, so opposite of opposite would be negative of negative of the given number. Therefore, opposite of the opposite would be same number.
a. A temperature rise of 15 degrees Fahrenheit.
The word "rise" is used in the given situation, which is [tex]15[/tex].
Opposite of [tex]15[/tex]: [tex]-15[/tex]
Opposite of opposite [tex]-15[/tex]: [tex]-(-15)=15[/tex]
Therefore, it will be [tex]15[/tex].
b. A gain of 55 yards.
The word "gain" is used in the given situation, which is [tex]55[/tex].
Opposite of [tex]55[/tex]: [tex]-55[/tex]
Opposite of opposite [tex]-55[/tex]: [tex]-(-55)=55[/tex]
c. A loss of 10 pounds.
The word "loss" is used in the given situation, which is [tex]-10[/tex].
Opposite of [tex]-10[/tex]: [tex]-(-10)=10[/tex]
Opposite of opposite [tex]10[/tex]: [tex]-(10)=-10[/tex]
c. A withdrawal of $2,000.
The word "withdrawal" is used in the given situation, which is [tex]-2,000[/tex].
Opposite of [tex]-2000[/tex]: [tex]-(-2000)=2000[/tex]
Opposite of opposite [tex]2000[/tex]: [tex]-(2000)=-2000[/tex]
