Question

Write an inequality for each sentence. Then solve the inequality.

1) A number minus 5 is greater than 25.


2) A number plus 18 is less than or equal to 20.

Answer 1

Let the number be 'x'

1)

`x - 5 > 25`
Plus 5 on both sides

`x > 30`
2)

`x + 18 \leqslant 20`
Minus 18 on both sides

`x \leqslant 2`
