Answer:
Infinitely many solutions
Step-by-step explanation:
If we have a system of equation like:
2x+y=4
6x+3y=12
If we make y the subject in the first equation and substitute into the second equation, we get:
6x+3(4-2x)=12
We expand to get:
6x+12-6x=12
6x-6x+12=12
Now the variable adds out to give:
12=12
This statement is true so the equation has infinitely many solution.
Answer: Mary is correct.
9/8 is an improper fraction, so we change it to 1 1/8.
Mary lives less than a mile from school, so we know that Thad lives farther since he lives a mile and 1/8 away, and Mary only lives 6/10 away, which is less than a mile.
