(Y×6+80×12):12:[9×87×7-(10000-4619)]=2
Mi a dat 400, e bine?

Answer 1

Răspuns:

Explicație pas cu pas:

Nu , nu e bine 400 , raspunsul e 240 .

(Y×6+80×12):12:[9×87×7-(10000-4619)]=2

(Y×6 + 960):12:[ 5481 -5381 ]=2

( Y×6 + 960 ) : 12 : 100 = 2

( Y×6 + 960 ) : 12  = 2 x 100

( Y×6 + 960 ) : 12  = 200

Y×6 + 960 = 200 x 12

Y×6 + 960 = 2400

Y×6 = 2400 - 960

Y×6 = 1440

Y = 1440 : 6

Y = 240

verificare :

( 240×6+80×12):12:[9×87×7-(10000-4619)]=

= ( 1440 + 960 ) : 12 : [ 5481 -5381 ] =

= 2400 : 12 : 100 =

= 200 : 100 =

= 2
