Question

1. assessment lana subtracts to find 52 - 39. which addition equation could lana use to check her answer?

a ( 13 + 26 = 39 )
b ( 39 + 52 = 91 )
c ( 13 + 39 = 52 )
d ( 52 + 13 = 65 )

Explanation:

Step1: Calculate subtraction result

$52 - 39 = 13$

Step2: Match check equation

For subtraction $a - b = c$, check with $c + b = a$.
Here $a=52$, $b=39$, $c=13$, so $13 + 39 = 52$.

Answer:

C. $13 + 39 = 52$
