8th Grade Math

Welcome to Eighth Grade Math with Mr. Scapellati!

EXTRA-CREDIT OPTION (in conjunction with the Unit 3 Test)
- If you would like to earn some extra credit, please complete the questions below neatly on loose leaf and graph paper.  Then attach this to the Unit 3 Exam (which should have a signature as well).  This must be submitted on or before 12/21.

1) Solve graphically:

-3x - 3y = 3
y = -5x - 17


2) Solve via substitution:

6a + 6b = -6
5a + b = -13


3) Solve using elimination:

-5m - 8r = 17
-17 = 2m - 7r 


4) Solve algebraically using a system:

The state fair is a popular field trip destination. This year the senior class at Morris High School and the senior class at Kent High School both planned trips there. The senior class at Morris High School rented and filled 8 vans and 8 buses with 240 students. Kent High School rented and filled 4 vans and 1 bus with 54 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.

TEST CORRECTIONS 

Students must follow this exact format to be eligible for earning points back:

For each exercise that was partially/completely wrong:

1) Write out the entire question.

2) Complete the exercise correctly with ample work.

3) Provide a brief reason as to why it was marked off the first time.

This should all be done neatly on loose leaf, stapled to the back of the signed test, and turned into the math bin within three days of class return.
