Answer: q=16
Step-by-step explanation:
if we suppose q=16
(q+4)/2=10

Answer:
I would tell you
Step-by-step explanation:
you need to put 2 y and 2 x and that you need to divide
Parallel: the lines have = slopes. We thus need 5/6 to equal 2/p. then 5p must equal 12, and p = 12/5. (answer)
Check: Is 5/6 = 2 / (12/5)? YES
Perp.: The lines have slopes that are negative reciprocals of one another.
Then -6/5 = 2/p, or
-6 2
---- = ----
5 p Thus, -6p = 10, and p = -5/3 (answer)
Answer: 300
Step-by-step explanation: 300+200=500
