D you put in 5 in place of where the n is
Answer:
D) n+ 4 = 9
Step-by-step explanation:
A. 9-n=13
= -n =13-9
-n =13-9 = -n =4
= n = -4
<em>Choi</em><em>ce</em><em> </em><em>A</em><em> </em><em>is</em><em> </em><em>incorre</em><em>ct</em>
<em>C</em><em>.</em><em> </em>2n =7
2n/2=7/2
n = 3.5
<em>Choi</em><em>ce</em><em> </em><em>C</em><em> </em><em>is</em><em> </em><em>incorrect</em>
D. n +4=9
n =9-4
n = 5
<em>Choi</em><em>ce</em><em> </em><em>D</em><em> </em><em>is</em><em> </em><em>corre</em><em>ct</em>
