Consider this equation (csc x+1)/cot x = cot x/(csc x +1) is it an identity?
levacccp [35]
Cross multiplying:-
cot^2 x = (csc x+ 1)(csc x + 1)

also  cot^2 x =  csc^2 x - 1  = (csc x + 1)(csc x - 1)  (Known Identitiy)

so the equation is not an identity

Jordan has 5/6 dvds as bob, so if jordan has 55 dvds how much does bob have?
Luba_88 [7]

Answer:

Bob has 66 dvds

Step-by-step explanation:

Let's assume

Bob has 'x' number of dvds

we are given

Jordan has 5/6 dvds as bob

so, Jordon will have

=\frac{5}{6}x

now, we are given jordan has 55 dvds

so, we can set it to 55

and then we can solve for x

\frac{5}{6}x=55

Multiply both sides by 6

6\times \frac{5}{6}x=6\times 55

5x=6\times 55

divide both sides by 5

\frac{5x}{5} =\frac{6\times 55}{5}

x=66

So,

Bob has 66 dvds
