69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
Answer:
125.7
I got this one right on my test yesterday :)
P=-24
-1/4(p+16)=2
Divide -1/4 on both sides
(P+16)=-8
Subtract 16 from both sides
P= -24
15. 13 1/3
16. 2 6/7
Those are the answers for 15 and 16. What you need to do is just use proportions for the similar sides :)
