Step-by-step explanation:
Answer:
The given equation is
y =
x
→ 
reciprocating both sides, we get
→
............(1)
→ Here x and y are Directly proportional to each other.
which means ,
→ x = k y , where k is constant of proportionality.
Or ,
= k ............................(2)
Equating (1) and (2),
k =
Answer
180
if your feeling nice can you give me a brainlest :)
your answer: 7 (b+x) + 7 (b+y)
If You do the distributive property you will get:
