Find the value of x. 140 40 2x. A 70 B 20 C 90 D 50​

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

What point is the projection of q on a) r b) s c) t
