8n+52=12(n+2)
distribute
8n+52 = 12n+24
subtract 8n from each side
52=4n +24
subtract 24 from each side
28 = 4n
divide by 4 on each side
7=n
Answer:

Step-by-step explanation:
We know that:

And we want to find:

Remember that there is a trigonometric identity that relates the
function with the
function

Then if
this means that:

Finally:

This is the concept of simultaneous equations; We are required to create the equations modelling the above information.
Suppose the number of movie tickets was x and the number of meal tickets was y.
Therefore;
Total number of tickets was:
x+y=22
Total amount earned was:
0.5x+2y=25
The simultaneous equations representing the information is:
x+y=22
0.5x+2y=25

Answer:
PQ = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° =
, then
cos60° =
=
=
=
( cross- multiply )
PQ = 8 × 2 = 16
