(1 point) o 5.17 o 5.07 o 4.07 o 4.17 item 8 item 9 item 10 item 11 item 12 item 13 item 14

Explanation:

Step1: Isolate the variable m

We have the equation $13.93 + m=18.0$. To find the value of m, we use the subtraction - property of equality. Subtract 13.93 from both sides of the equation.
$m = 18.0−13.93$

Step2: Perform the subtraction

$18.0−13.93 = 4.07$

Answer:

4.07
