Answer:
x=0
Step-by-step explanation:
When you raise a negative integer (in this case -1) to an even integer (30), the end result will be positive (1), but when you raise it to an odd integer (31), the end result will be negative (-1). The sign of the product fluctuates between positive and negative depending on the type of integer it’s raised to.
Answer:
![Total = \$5d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%245d%20-%202)
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
![A = \$d](https://tex.z-dn.net/?f=A%20%3D%20%5C%24d)
--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount
![A = \$d](https://tex.z-dn.net/?f=A%20%3D%20%5C%24d)
Substitute
for A in
![F = 2 * \$d](https://tex.z-dn.net/?f=F%20%3D%202%20%2A%20%5C%24d)
![F = \$2d](https://tex.z-dn.net/?f=F%20%3D%20%5C%242d)
Substitute
for F in ![Y = F - 2](https://tex.z-dn.net/?f=Y%20%3D%20F%20-%202)
![Y = \$2d - 2](https://tex.z-dn.net/?f=Y%20%3D%20%5C%242d%20-%202)
The total amount is calculated by adding the earnings of Alice, her friend and you
![Total = A + F + Y](https://tex.z-dn.net/?f=Total%20%3D%20A%20%2B%20F%20%2B%20Y)
![Total = \$d + \$2d + \$2d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%24d%20%2B%20%5C%242d%20%2B%20%5C%242d%20-%202)
![Total = \$5d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%245d%20-%202)
<em>Hence, the total earnings is 5d - 2</em>
