( x * 70 = 4900 )( x = \frac{4900}{70} )( x = 70 )
( x : 80 = 700 )( x = 80 * 700 )( x = 56,000 )
( 64,000 : x = 40 )( x = \frac{64,000}{40} )( x = 1600 )
Ответ:
( x * 70 = 4900 )
( x = \frac{4900}{70} )
( x = 70 )
( x : 80 = 700 )
( x = 80 * 700 )
( x = 56,000 )
( 64,000 : x = 40 )
( x = \frac{64,000}{40} )
( x = 1600 )
Ответ:
x = 70x = 56,000x = 1600
