So try to isolate a by division and such K=4a+9ab we use reverse dstributive which is ab+ac=a(b+c) so undistribute a 4a+9ab=a(4+9b) k=a(4+9b) divide both sides by (4+9b) =a a=
1. simplify 42/60 to 7/10 (42/60 divided by 2 is 21/30, 21/30 divided by 3 is 7/10) 2. if 10 x 10 = 100 than 7 x 10 = 70 so that would make it 70/100 which is 70% so 70% is the answer
Hope this helps ;) Please don't forget to mark as brainliest answer!
