You need to memorize the definitions of all the trig functions and then this type of problem will be easy for you.
Answer:
x=2
Step-by-step explanation:
Distribute the 9
9x+9=25+x
Move x to one side. I prefer to keep the x term positive, so I would move the term on the right to the left in this situation.
8x+9=25
Isolate the x term
8x=16
Isolate the variable
x=2
Do the easiest percentages first:For me its this order to figure it out,
20% of 60 is 12 -double 10%-
5% of 60 is 3 -half of 10%-
15% of 60 is 9 - 10% + 5%-
60% of 60 is 36 -10% x 6-
Add all these together so 12+3+9+36 =60 so he doesn't need to print anymore double check this though!!
