Write an expression for the number of dimes.

Answer 1

5q-2=x

Step-by-step explanation:

let the number of quarters is q and no. of dimes is x

five times the number of quarter means

5×q=5q

less than 2 means

-2

so we get

5q-2=no. of dimes

5q-2=x

The number of dimes is $2$ less than $5$ times the number of quarters i.e.

$5q-2$

Hence, the number of dimes can be expressed as $5q-2$
