Answer: x= -1
Step-by-step explanation:
In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have
- 4x +4-x
- 4x-x=1
- 3x+4-4 =1-4
- 3x/3 = -3/3
- x= -1

Answer:
Each person will pay $ 7.20
Step-by-step explanation:
First we find the total bill
Pizza $18.60
Salad $2.50
<u>Soda $2.25</u>
Total $ 23.35
Sales Tax would be= 8 1/4% of $ 23.35 =$ 1.926= $ 1.93
Tip = 15% of $ 23.35= $ 3.5025
Total Bill paid= $ 23.35 + $ 1.93+ $3.50= $ 28.7825 or $ 28.78
Now dividing the bill among 4 persons = $ 28.78/4= $ 7.196 or $ 7.20
Paying the bill equally is better and convenient than paying alone as each person gets an equal share of pizza, salad and the soda.
There is no problem on here
