37064 - 64 x ( 82 + 42966 : 217 )
= 37064 - 64 x 280
= 37064 - 17920
= 19144

37064 - 64 x ( 82 + 42966 : 217 )
= 37064 - 64 x ( 82 + 198 )
= 37064 - 64 x 280
= 37064 - 17920
= 19144
b) 320 - ( 120 x 5 + 95, 25 + 5,25 ) + 864 : 12 x 12,5

= 520
37064 - 64 x ( 82 + 42966 : 217 )

chúc bn hok tốt @_@
124+(118-x)=217
=>118-x=217-124
=>x=118-93
=>x=25
156-(x+61)=82
=>x+61=156-82
=>x=74-61
=>x=13
\(\frac{x+91}{81}+\frac{x+92}{82}+\frac{x+93}{83}=3\)
\(\frac{x+91}{81}-1+\frac{x+92}{82}-1+\frac{x+93}{83}-1=0\)
\(\frac{x+10}{81}+\frac{x+10}{82}+\frac{x+10}{83}=0\)
\(\left(x+10\right)\left(\frac{1}{81}+\frac{1}{82}+\frac{1}{83}\right)=0\)
=> x + 10 = 0 (vì \(\left(\frac{1}{81}+\frac{1}{82}+\frac{1}{83}\right)\ne0\))=> x = -10
82 - ( 15 + x ) = 92
15 + x = 82 - 92
15 + x = -10
x = ( -10 ) - 15
x = -25
82 - ( 15 + x ) = 92
15 + x = 82 - 92
15 + x = - 10
x = - 10 - 15
x = - 25
Vậy x = - 25
E=92x164-64x(82+10)

E92x(164-64)
E=92x100
E=9200.
k minh voi.
E=9200
