\(x\times48=490,1-125,33\)
\(x\times48=364,77\)
\(x=364,77\div48\)
\(x=7,599375\)
Vậy, `x = 7,599375`
`c)`
\(42,75+x\div5=94,5\)
`x \div 5= 94,5 - 42,75`
`x \div 5 = 51,75`
`x = 51,75 \times 5`
`x = 258,75`
Vậy, `x = 258,75`
`d)`
\(x-\dfrac{3}{4}+\dfrac{1}{4}=3\dfrac{1}{3}\)
\(x-\left(\dfrac{3}{4}-\dfrac{1}{4}\right)=\dfrac{10}{3}\)
\(x-\dfrac{2}{4}=\dfrac{10}{3}\)
\(x=\dfrac{10}{3}+\dfrac{2}{4}\)
\(x=\dfrac{23}{6}\)
Vậy, \(x=\dfrac{23}{6}\)
\(x+x\times3=48\)
\(x\times3=48\div2x\)
\(x\times3=24\)
\(\Rightarrow x=24\div3\)
Vậy \(x=8\)
a, X x (1/3 + 1/6)=48
3/6 x X = 48
X = 96
b,x : 2/5 = 5/9
x= 25/18
c, (002 là sao bạn)
d,X - 23,7 = 72,3
X= 96
e, (108-48) : X =30
60 : X = 30
X = 2
f, (59,35 + 40,65) : X = 50
100 : X = 50
X = 2
\(x:3\times48+x:4\times36=1500\)
\(x\times\frac{1}{3}\times48+x\times\frac{1}{4}\times36=1500\)
\(x\times16+x\times9=1500\)
\(x\times\left(16+9\right)=1500\)
\(x\times25=1500\)
\(x=1500:25\)
\(x=60\)
a) \(136-x:48-27,8-2,2=92\)
\(136-x:48-30=92\)
\(106-x:48=92\)
\(x:48=106-92\)
\(x:48=14\)
\(x=14\times48\)
\(x=672\)
b) \(43,7-x-8,92+5,22=0,348\times19\)
\(40-x=6,612\)
\(x=40-6,612\)
\(x=33,388\)
136-x:48=27,8+92
(=) 136-x:48=119,9
(=) x:48=136-119,9
(=) x:48=16,1
(=) x=16,1.48
(=) x=772,8
làm nhầm mất rồi
136-x:48=27,8+92
(=) 136-x:48=119,8
(=) x:48=136-119,8
(=) x:48=16,2
(=) x=16,2.48
(=) x=777,6
48 * x - x + 53 * x = 7900
,=> x *( 48 - 1 + 53 ) = 7900
=> x * 100 = 7900
=> x = 7900 : 100
=> x = 79
Vậy x = 79
\(a,y\times2,8+5,2\times y=48\\ y\times\left(2,8+5,2\right)=48\\ y\times8=48\\ y=\dfrac{48}{8}=6\\ ---\\ b,y\times12,25-y+y\times2,75=1050\\ y\times\left(12,25-1+2,75\right)=1050\\ y\times14=1050\\ y=\dfrac{1050}{14}=75\)
a: \(y\cdot2,8+y\cdot5,2=48\)
=>\(y\left(2,8+5,2\right)=48\)
=>\(8y=48\)
=>\(y=\dfrac{48}{8}=6\)
b: \(y\cdot12,25-y+y\cdot2,75=1050\)
=>\(y\left(12,25-1+2,75\right)=1050\)
=>\(y\cdot14=1050\)
=>\(y=\dfrac{1050}{14}=75\)
x - ( 48 - 24 x 2 : 6 - 3 ) = 0
x = 48 - 24 x 2 : 6 - 3
x = 48 - 48 : 6 - 3
x = 48 - 8 - 3
x = 40 - 3
x = 37
Vậy x = 37
Tham khảo nha !!!
\(x\times48=490,1-125,33\)
\(x\times48=364,77\)
\(x=364,77:48\)
\(x=7,599375\)
`x xx 48 = 490,1 - 125,33`
`x xx 48 = 364,77`
`x=364,77 :48`
`x=7,599375`
