460+85.4=( x +200) ÷ 4
5x=125
460+85.4=(x+200).4
\(460+85.4=\)\(\left(x+200\right).4\)
\(460+340=\left(x+200\right).4\)
\(800\) \(=\left(x+200\right).4\)
\(\Rightarrow\left(x+200\right).4=800\)
\(\left(x+200\right)\) \(=800:4\)
\(x+200\) \(=200\)
\(x\) \(=200-200\)
\(x\) \(=0\)
Vậy x = 0
tìm x, biết :
460+85.4=(x-200) :4
ta có 460+85.4=(x-200):4
<->460+340=(x-200):4
<-> 800=(x-200):4
<->800.4=x-200
->x=3200+200=3400
tìm x biết:460+85.4=(x+200):4.kết quả x là?
Ta có: 460+85,4=(x-200):4
suy ra 460+340=(x-200):4
suy ra 800=9x-200):4
suy ra 800:4=x-200
suy ra x=3200+200=3400
a)460+85.4=(x+200).4
b)x+5.2-(32+16.3:16-15)=0
a) 460 + 85 * 4 = ( x + 200 ) * 4
460 + 340 = ( x + 200 ) * 4
800 = ( x + 200 ) * 4
x + 200 = 200
x = 0
b) x + 5 * 2 - ( 32 + 16 * 3 : 16 - 15 ) = 0
x + 10 - ( 32 + 3 - 15 ) 0
x + 10 - 20 = 0
x - 10 = 0
x = 10
a) \(460+85.4=\left(x+200\right).4\)
\(\Rightarrow460+340=4x+800\)
\(\Rightarrow-4x=800-460-340\)
\(\Rightarrow-4x=0\)
\(\Rightarrow x=0\)
Vậy x = 0
b) \(x+5.2-\left(32+16.3:16-15\right)=0\)
\(\Rightarrow x+10-\left(32+3-15\right)=0\)
\(\Rightarrow x+10-20=0\)
\(\Rightarrow x-10=0\)
\(\Rightarrow x=10\)
Vậy x = 10
a, \(460+85.4=\left(x+200\right)4\)
\(460+340=\left(x+200\right)4\)
\(800=\left(x+200\right)4\)
\(\Leftrightarrow x+200=\frac{800}{4}\)
\(\Leftrightarrow x+200=200\)
\(\Rightarrow x=200-200\)
\(\Rightarrow x=0\)
Vậy \(x=0\)
mình đang hơi bận, cho dù mình thấy bài này cũng dễ nhưng mình cần giúp cho nhanh
460+85.4=(x+200).4
Tìm x biết:
a) x - 280 : 35 = 5.54
b) (x - 280) : 35 = 56 : 5
c) x : 15 + 42 = 13 + 25.8
d) (x - 128 + 20) : 192 = 0
e) 460 + 85.4 = (x + 200).4
f) x + 5.2 - ( 32 + 16.3 : 16 - 15) = 0
GIÚP MÌNH NHA!
2.tìm x
C) x-6:2-(48-24.2:6-3)=0 D)x:15+42=15+25.8
E) x5.2-(32+16.3:6-15)=0 F)460+85.4=(x+200):4
460=85.4=x+175 phần 5+30
Tìm x biết:
a) 5 ( x+35)=515
b) (x+40).15=75.12
c) 460+85.4=(x+200):4
Tính nhanh: (23.94+93.45):(92.10-92)
a. 5(x+35)=515
=> x+35=515:5
=> x+35=103
=> x = 103-35
=> x = 68
b. (x+40).15=75.12
=>(x+40).15=900
=>x+40=900:15
=>x+40=60
=>x=60-40
=>x=20
c.460+85.4=(x+200):4
=>460+340=(x+200):4
=>800=(x+200):4
=>800.4=x+200
=>3200=x+200
=>x=3200-200
=>x=3000
5(x+35)=515
x+35=515/5
x+35=103
x=103-35
x=68
còn câu tính nhanh nữa giải dùm mình đi
