For our system, we suppose that x is the number of tickets, y is the number of drinks and z is the number of bags of popcorn.
Devin bought <u>three tickets, one drink, and one bag of popcorn for $43.75.</u>
This means that:
Neil bought <u>one ticket, three drinks, and two bags of popcorn for $27.75</u>.
This means that:
Jung bought <u>two tickets, two drinks, and one bag of popcorn for $34.</u>
This means that:
The system is:

x = 6
Step-by-step explanation:
2x - 5 = 7

Plz mark brainliest thanks
For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
87 in expanded form is two simple digits of place value
Ex. 80+7
6 x 532 in expanded form is 6 x 500 + 30 + 2
