Answer:
Step-by-step explanation:
7/12-2/5
We will find the LCM of it to make the denominators same.
Which is 60
Now to make denominators same
7/12×5/5
= 35/60
2/5×12/12
= 24/60
Now using these like values
35/60-24/60
= 11/60

q+6)=
–
20
5q–30=
–
20
Add -5 to both sides
Subtract -5 from both sides
Multiply both sides by -5
Divide both sides by -5

Step-by-step explanation:
Just use a calculator and type in the 
Step-by-step explanation:
cot x / (1 + csc x)
Multiply by conjugate:
cot x / (1 + csc x) × (1 − csc x) / (1 − csc x)
Distribute the denominator:
cot x (1 − csc x) / (1 − csc²x)
Use Pythagorean identity:
cot x (1 − csc x) / (-cot²x)
Divide:
(csc x − 1) / cot x
