Question

What are the constants in the expression below? Check all that apply.

Answer 1

Answer:  The correct options are :

(B) $-3.7,$

(C) $\dfrac{1}{3},$

(F) $12.$

Step-by-step explanation:  We are given to select all the constants in the following expression :

$E=12+x-3.7-8y+\dfrac{1}{3}~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

in an algebraic expression, the constants are those terms which are not multiplied to some unknown variables.

In the given expression (i), there are two unknown variables x and y.

So, the terms which are not multiplied by x or y are the constants in the expression.

Therefore, the required constants are

$12,~~-3.7,~~\dfrac{1}{3}.$

Thus, (B), (C) and (F) are the correct options.

Answer 2

Constants are numbers alone with no variables.

The constants are: 12, -3.7, 1/3
