Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

Given: p: 2x = 16 q: 3x – 4= 20 which is the converse of p - q? if 2x + 16, then 3x - 4 20. if 3x –4 +20, then 2x # 16. lf 2x = 16, then 3x - 4 = 20. lf 3x – 4= 20, then 2x = 16. o o
