Answer:
7^(1-3+1) = 7^-3
Step-by-step explanation:
Here is the rule you should know: when multiplying powers of the same base you add the exponents ans when dividing powers of the same base you subtract the exponents.
Also, if there is no number at the exponent, it is 1.
Child = $5.70
Adult = $9.80
- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)
For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
y=-3 and then x=-1 =-3:-1
