Simplify the following inequality 3x + 12 ≥2(4x + 3) −21

i need the answer asap

Solve 2x+y=3 x+y=5 in substitution method

Atriangular field has sides of lengths 21, 39, and 41 yd. find the largest angle. (round your answer to the nearest degree.)

Hich equation can pair with x + 2y = 5 to create an inconsistent system? 2x + 4y = 3 5x + 2y = 3 6x + 12y = 30 3x + 4y = 8
