3/4(x) + 5 - 1/2(x) = 3
If x = -8 then,
3/4(-8) + 5 - 1/2(-8)
-6 + 5 - (-4)
-6 + 9
3 = 3
Your answer would be that x = -8
You're welcome.

Answer: 12 packages with 5 notebooks and 6 pencils in each package.
Step-by-step explanation:
The greatest common factor of 60 and 72 is 12. Thus divide both numbers(60 and 72) by 12 to get 5 and 6. Thus, Miss Smith made 12 packages with 5 notebooks and 6 pencils in each package.
Answer: Max is a very intelligent boy.
Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
