Question

write down a pair of integers whose (a) sum is —7(b) difference is —10 (c)sum is 0​

Answer 1

Answer:

(a) (-5) + (-2) = -7.

(b) (-8) - 2= -10.

(c) (-10)+ 10= 0.

Answer 2

A) -9 and 2 are the pair of integers  whose sum is -7

B) -8 and 2 are the pair of integers  whose difference is -10

C) 5 and -5 are the pair of integers  whose sum is 0

Solution:

Given that,

We have to write down the pair of integers

a) sum is -7

Consider the following,

Let the integers be -9 and 2

Now find the sum

sum = -9 + 2 = -7

sum = -7

b) difference is -10

Let the integers be -8 and 2

Then,

Difference = -8 - 2

Difference =  -10

c) sum is 0​

Let the integers be 5 and -5

Then,

sum = 5 + ( - 5 )

sum = 0

Thus 5 and -5 are the pair of integers  whose sum is 0
