Question

Write the inequality from the verbal expression.

The difference of a number times seven and five is greater than twenty-two.

Answer 1

Let the number be x

5 times of x=5x

And 7 means add 7=5x+7

Their sum = 5x+7=22

Therefore 5x=22–7=15

5x=15 dividing by 5

x=3

Verification

5x+7=22

5*3+7=22

15+7=22

22=22

L.H.S.= R.H..S

Ans The number is 3

Or.

(x)*(7+5) ≥ 22
