Question

4) The sum of two integers is - 104. If one of them is 19, find the other.
5) Write all the integers between - 18 and 9.
6) Simplify:
(– 25 + 21) – (62 – 7) + 20
7) Arrange the following integers in ascending order:
-20, -35, +15, - 40, +25, - 15, - 24​

Answer 1

Step-by-step explanation:

4)Let the other integer be x

or,19+x=-104

or,+x=-104-19

or,+x=-123

*the other integer is -123

Answer 2

Step-by-step explanation:

Answer 4 -

let x and y the two integers whose sum is -104.

then, we have,

x + y = -104

according to question one of them is 19.

therefore, if x=19.

then,

19 + y = -104

by solving this

y = -104 -19

y = -123

Answer 5 -

the following are the integers between -18 and 9.

-17, -16, -15, -14, -13, -12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8.

Answer 6 -

(-25 + 21) - (62 - 7) + 20

solve the brackets first,

-4 -55 +20

solve this

we get,

-39

Answer 7 -

-40, -35, -24, -20, -15, +15, +25
