One shirt costs $9 dollars and the other shirt cost 27$ dollars. If you split 36$ in half you will have 18 and another 18, but since one shirt cost twice as much as the other you would split 18 in half to get the lower cost of the shirt that cost less money then you would find a number to add to 9( which is 27)so you would get $36 in total.
Answer: ab -12
Given that y is 12 less than the product of a and b.
The product of a and b is the multiplication of a and b:
a x b = ab
12 less than the product will mean that we need to take away 12 from ab, so
y = ab - 12

Answer:
x is equal to 2
Step-by-step explanation:
Order of Operations:
PEMDAS
P: Parenthesis
E: Exponents
MD: Multiplication/Division
AS: Addition/Subtraction
Remember to do them in order.
E.G: 8(2+3)²-4/2
You do first the parenthesis(2+3), which is 6
Multiply 6 by 6(rule of exponents), which is 36.
Multiply 36 by 8, which is 288.
Divide 288 by 2, which is 144.
Subtract 144-2. It is 142.
Answer: 142
Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
