Answer:
the answer to the whole equation is x=30.
Step-by-step explanation:
do 2/3(2) and -1/2(3)
4/6x and -3/6x
add the -3/6x to the other side

Doing an X and Y table i do not see that they will have the same amount. Adrian will always have 4 more comic books than Roy
Answer:
12
Step-by-step explanation:
The 2 lines are equal in length. Therefore:-
ST = 21 - 9 = 12
Cosx= sin(90-x)
From the RHS,
sin(90-x)= sin90cosx-cos90sinx
Since sin90=1, cos90=0
sin90cosx-cos90sinx=cosx-0=cosx (proven)
It is different from how long you had did it and you are using a way more complicated system than before.
