Choose the expression that represents “three less than seven times a number.

Three less than seven times a number

to write it in terms of expression

Let us assume that the number is x

now it says

seven times a number

So it becomes 7x

and then it says

three less than seven times a number

that is 3 less than 7x

It means we have to subtract 3 from 7x

So final answer should be

7x-3

Second option is correct 7x-3

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
