tìm x biết x*16,01-x/100=76
x*16,01 - x/100 = 76
x*16,01-x/100=76
x*16,01-x*\(\frac{1}{100}\)=76
x*(16,01-0,01)=76
x*16=76
x=4,75
X×16,01-x/100=76
Bài 4: Tìm x:
a) X x 16,01 - \(\frac{x}{100}\) = 76
b) X x 1,2 + X x 2,3 + 6,5 x X = 150
Mình giúp đc bn câu B nhé
b) X x 1,2 + X x 2,3 + 6,5 x X = 150
X x ( 1,2 + 2,3 + 6,5 ) = 150
X x 10 = 150
X = 150 : 10
X = 15
Câu A mk nghĩ ra rồi :
a ) X x 16,01- \(\frac{x}{100}\)= 76
X x ( 16,01 - 0,01 ) = 76
X x 16 = 76
X = 76 : 16
X = 4,75
Đúng thì k mk nhé

TÌM X:
a) X x 16,01 - X = 76
b) X : 0,25 + X x 11 = 36
a) X(16,01-0,01)=76
X x 16 = 76
X = 4,75
b) X x 4 + X x 11 = 36
X ( 4 + 11 ) =36
X x 15 = 36
X = 2,4
x*4,8 cộng x *5,2 bằng 16,01
\(\Rightarrow x\times\left(4,8+5,2\right)=16,01\\ x\times10=16,01\\ x=16,01:10=1,601\)
Tìm x, biết:
\(\left|\frac{x^3+x^4-x^5-x^6+x^7+14}{x^6+4}\right|=\sqrt{76}+\sqrt{100}\)
x*(4,8 cộng 5,2) bằng 16,01
X * ( 4,8+5,2) = 16,01
X* 10 = 16,01
X = 16,01: 10
X= 1,601
Vậy x = 1,601
Tìm Y :
a) 24 x y + 76 x y = 1000
b) 125 x y - 100 x y = 1000
a) \(24\times y+76\times y=100\)
\(\Rightarrow\left(24+76\right)\times y=100\)
\(\Rightarrow100\times y=100\)
\(\Rightarrow y=100:100\)
\(\Rightarrow y=1\)
b) \(125\times y-100\times y=1000\)
\(\Rightarrow\left(125-100\right)\times y=1000\)
\(\Rightarrow25\times y=1000\)
\(\Rightarrow y=1000:25\)
\(\Rightarrow y=40\)
a)\(=>y=1000:\left(24+76\right)=1000:100=10\)
b(\(=>y=1000:\left(125-100\right)=1000:25=40\)
