Answer:
45 student tickets and 30 adult tickets
Step-by-step explanation:
You can check your work by plugging both answers into both of the original equations. :)
Ummm we can't answer that question if there isn't a question , but if you are bored I understand why you put that ^-^
Part A is irrational, but Parts B and C are both rational.
We know that Part A is irrational because an irrational number added to a rational number is still irrational. Also, an irrational number multiplied by a rational number is still irrational.
With Part B, we have an irrational number in the square root of 7. However, it is then squared to give us 7. This leaves us with 7 times a^2 which is rational. Two rational numbers multiplied still give us a rational number.
Finally, Part C only involves adding and multiplying rational numbers. Since that can only yield rational numbers, it must be rational.
Answer: -4
Step-by-step explanation:
No options were provided, but i'll simplify this expression.
*the number being NEXT to the parenthesis indicates that you have to multiply.
This expression involves the distributive property. This is when you have a number followed by an equation in parenthesis, like 2(3+1). To solve it, you multiply the number outside of the parenthesis by <u>each number</u> inside them.
-2(5-3)
-2(5) - -2(3)
-10 + 6
-4
So -2(5-3) simplifies to -4. I hope this could help!!
