x + 100 = 500 x 2
Tính giá trị biểu thức :
a) 500 + 500 + 500 + ( 100 x 2 )
b) 700 + 300 + ( 100 x 10)
a, 500+500+500+(100 x 2)
=500 x 3+ 100x2
=1500+200
=1700
b, 700+300+(100 x 10)=700+300+1000=1000+1000=2000
k minh nha
Tìm x :
a) x . x . x = 125
b) ( x + 500 ) = 1000 - 200 .2
c) [( x + 10 ) . 100 ] = 500 + 500 . 10
a) x . x . x = 125
x3 =125
x3 = 53
= > x = 5
b) ( x + 500 ) = 1000 - 200 . 2
x + 500 = 1000 - 400
x + 500 = 600
x = 600 - 500
x = 100
c) [( x + 10 ) . 100 ] = 500 + 500 . 10
( x + 10 ) . 100 = 500 + 5000
( x + 10 ) . 100 = 5500
x + 10 = 5500 : 100
x + 10 = 55
x = 55 - 10
x = 45
Tính nhẩm.

83 000 : 1 000 = 83
b) 720 : 10 : 8 = 72 : 8 = 9
1 500 : (5 x 100) = 1 500 : 5 : 100 = 300 : 100 = 3
60 000 : 1 000 x 6 = 60 x 6 = 360
x + 100 = 500 : 2
x + 500 = 650
x +100 = 500 : 2
x+ 100 = 250
x=250-100
x= 150
x+500= 650
x= 650-500
x= 150
k giúp mik nhé
x + 100 = 500 : 2
x + 100 = 250
x = 250 - 100
x = 150
x + 500 = 600
x = 600 - 500
x = 100
K mk mk k lại
Hứa luôn
b) 200 x 4 = ...... 300 x 2 = ......
200 x 2 = ...... 300 x 3 = ......
400 x 2 = ...... 500 x 1 = ......
100 x 4 = ...... 100 x 3 = ......
b) 200 x 4 = .800..... 300 x 2 = ..600....
200 x 2 = .400..... 300 x 3 = ...900...
400 x 2 = ...800... 500 x 1 = ..500....
100 x 4 = ..400.... 100 x 3 = .300.....
x + 100 - 200 = 500 x 2 + 100.
x + 100 - 200 = 500 x 2 + 100
x + 100 - 200 = 1100
x + 100 = 1100 + 200
x + 100 = 1300
x = 1300 - 100
x = 1200 k mk,mk sẽ k lại bn
x+100-200=500x2+100
x+100-200=1000+100
x+100-200=1100
x+100 =1300
x =1200
vậy x=1200.
\(x+100-200=500\times2+100\)
\(x-100=1000+100\)
\(x-100=1100\)
\(x=1100+100\)
\(x=1200\)
Tìm x : [ 500 : (x - 10) x 2 ] + 100 = 200
Tìm x :
[ 500 : (x - 10) x 2 ] + 100 = 200
=> 500 : ( x - 10 ) x 2 = 200 - 100
=> 500 : ( x - 10 ) x 2 = 100
=> 500 : ( x - 10 ) = 100 : 2
=> 500 : ( x - 10 ) = 50
=> x - 10 = 500 : 50
=> x - 10 = 10
=> x = 10 + 10
=> x = 20
Vậy x= 20
Tìm x : [ 500 : (x - 10) x 2 ] + 100 = 200
[500 : (x-10) x 2] + 100 = 200
500 : (x-10) x 2 = 100
=> 500 : (x-10) = 50
=> x - 10 = 10
=> x =20
Tìm x :
x + 500 = 100 x 2
x+500=100x2
x+500=200
x=200-500
x=-300
đúng rồi bn nhé
*** mk nha
x + 500 = 100 x 2
x + 500 = 200
x = 200 - 500
x = - 300
Vậy x = - 300
Như vầy có đúng ko nhỉ ?
x + 500 = 100 x 2
x + 500 = 200
x = 200 - 500
x = -300
Nhớ tk cho mk nha mọi người
