Question

which is the solution to the inequality represented by "half a number decreased by 5 less than or equal to seven"

Answer 1

Step-by-step explanation:

Let a number be 'x'

half of it would be x/2

Now According to the question,

5-x/2<or=7

-x/2<or=2

Now multiplying both sides by -1

x/2>=-2

therefore x is greater than or equal to -4
