Answer:
7.5
Step-by-step explanation:
y=1.6x + 48
so you put 60 where y is
60=1.6x + 48
then you subtract 48 from both sides
60-48=1.6x + 48-48
12=1.6x
then you divide 1.6 by both sides
12/1.6=1.6/1.6x
so your answer will be
7.5=x
and also if you put 7.5 where x is in the equation you will get 60 just so you know that.

Answer:
see explanation
Step-by-step explanation:
Using the Addition/ Subtraction formulae for cosine
Consider the left side
cos(x - y) - cos(x + y)
= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute
= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms
= 2sinxsiny = right side ⇒ proven
