Answer: $54
The shirts in total cost $30 and with the additional $30 cost of the jeans the total price without a discount is $60. You then take the discount and turn it into a decimal (0.10) and multiply it by the $60 total. This gives you 6, which is the amount of money you take off, which means the total is $54
Answer:
B
Step-by-step explanation: it is easy
Answer:
a = π n for n element Z
Step-by-step explanation:
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
