Question

If n =r+ 5 and r = 3, then n =

Answer 1

Answer:

n = 8

Step-by-step explanation:

n = r + 5

n = (3) + 5

n = 8

Answer 2

Answer:

$\boxed {\tt n=8}$

Step-by-step explanation:

We know that n is equal to r plus 5, or

$n=r+5$

We want to find n when r is equal to 3. Therefore, we must substitute 3 in for r.

$n=r+3 \ and \ r=3$

$n=5+3$

Add 5 and 3.

$n=8$

n is equal to 8 when r is equal to 3.
