Question

1. What inequality represents the sentence?

The product of a number and 12 is no more than 15.

12n < 15
12n > 15
12n ≥ 15
12n ≤ 15

Answer 1

12n ≤ 15

Explanation:

In equality,

a < b = a is less than b,

a > b = a is greater than b,

a ≥ b = a is greater or equal to b,

a ≤ b = a is less or equal to b,

Here, the given phrase,

The product of a number and 12 is no more than 15.

⇒ The product of a number and 12 is less than equal to 15,

If n represents the number,

∵ Product of n and 12 = 12,

⇒ 12n ≤ 15

Which is the required inequality.

Answer 2

No more means less than or equal to;
12n
`\leq`15
