8 - ? = -1. the missing number would be 9.
This equation has infinite solutions, any real number makes it true.
Lst question: x = 5, y = 7
2nd question: x = -1, y = 5
3rd question: x = 98, y = 80
Answer:
It's c) y = 15x +200
Step-by-step explanation:
First divide the total cost by the number of students using two values of the table:
1500/100 = 15
This is the number that multiply x in the equation.
In the options given, there is just one equation that have 15 multipling x, so that must be the answer
