Answer 1

QUESTION

If x = 2n + 1, what is the value of x when n = 10?

EXPLANATION

To find the value of x when n is equal to 20, all you have to do is substitute n with 10 in the equation you are given.

Substitute:

$\bf x=2(10)+1$

Your new equation is $\bf x=2(10)+1$

Now you need to multiply the 2 and 10 to take out the parentheses.

$\bf 10 \times 2=20$

Your new equation is $\bf x=20+1$

Lastly, you have to add 20 and 1

$\bf 20+1=21$

That means your answer is x = 21
