Question

300_b×8_109=47
(48×c+216):40=27​

Answer 1

Răspuns:

Explicație pas cu pas:

300 -b x 8 - 109 = 47

300 - b x 8 = 47 + 109

300 - b x 8 = 156

b x 8 = 300 - 156

b x 8 = 144

b = 144 : 8

b = 18

( 48 x c + 216 ) : 40 = 27

( 48 x c + 216 ) = 27 x 40

48 x c + 216 = 1080

48 x c = 1080 - 216

48 x c = 864

c = 864 : 48

c = 18
