If n denotes a number to the left of 0 on the number line such that the square of n is less than \small \frac{1}{100}, then the reciprocal of n must be

The reciprocal of n must be less than 10.

Step-by-step explanation:

It can be inferred from the question given that n is not a negative number.

But,

<

Find the square root of both sides,

n <

⇒ n <

n < 0.1

The reciprocal of n can be estimated as;

<

< 10

The reciprocal of n is less than 10.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
