First part : you can purchase 6 boxes of tissues for $15. how much does each box cost? write the information you have been given as a ratio. second: next, set up a proportion to determine the cost of just one box of tissues. don't forget to write a ratio using words first
= =
solve for missing information:
=
last: rather than set up a proportion, you can always just

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17
