Question

Математика: 1) 8(x-1,4)=0,56 2) (4,6-x)*19=4,18 3) (51,32+x)*0,12=72 4) 17,28: (56-x)=36

Ladnaya56 · Answer

А) 8 * (х - 1.4) = 0.56х - 1.4 = 0.56 : 8х - 1.4 = 0.07х = 1.4 + 0.07х = 1.47Б) (4.6 - х) * 19 = 4.184.6 - х = 4.28 : 194.6 - х = 0.22х = 4.6 - 0.22х = 4.38В) (52.32 + х) * 0.12 = 7252.32 + х = 72 : 0.1252.32 + х = 600х = 600 - 52.32х = 547.68Г) 17.28 : (56 - х) = 3656 - х = 17.28 : 3656 - х = 0.48х = 56 - 0.48х = 55.52...
