30 point, anyone? Totally stumped. Match each expression in column A with an equivalent expression from column B. SHOW OR EXPLAIN YOUR REASONING (teacher did all caps for some reason)
Column A
A. 12r+t−4r+6t
B. (12r+2t)−(4r+10t)
C. 12(r+t)−6(r+t)+4(r+t)−2(r+t)
Column B
1. 8(r−t)
2. 8(r+t)
3. 8r+7t

Henry's butcher shop uses an electronic scale that measures to 1/100 of a pound. which is the most accurate measurement based on the limitations of the scale that might be found on a package of meat sold by henry?

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
