Answer:
(0,0) is a solution to n=m and n=4m
Step-by-step explanation:
For the first equation, If u insert 0 as m into n=m
n=(0) then n will equal 0.
For the second equation, if u insert 0 as m in n=4m
n=4(0) then n will also equal 0.
So the answer is (0,0) is a solution to n=m and to n=4m
Hope this helps :)
Answer: 312 students purchased a ticket
Step-by-step explanation:
Let x represent the number of raffle tickets sold to parents.
Let y represent the number of raffle tickets sold to students.
The school sold 371 tickets. This means that
x + y = 371
x = 371 - y
The parent tickets cost $6 each and the student tickets cost $1.50 each and the school raised a total of $822. This means that
6x + 1.5y = 822 - - - - - - - -1
Substituting x = 371 - y into equation 1, it becomes
6(371 - y) + 1.5y = 822
2226 - 6y + 1.5y = 822
- 6y + 1.5y = 822 - 2226
- 4.5y = - 1404
y = -1404/-4.5
y = 312
x = 371 - y
x = 371 - 312
x = 59
