X x 27 + X x 30 + X x 43 = 210 500
X x ( 27 + 30 + 43 ) = 210 500
X x 100 = 210 500
x = 210 500 : 100
x = 2105
Chúc em học tốt nhé
TL:
X x 27 + X x 30 + X x 43 = 210 500
X x (27 + 30 + 43) = 210 500
X x 100 = 210 500
X = 210 500 : 100
X = 2105

a)\(\Leftrightarrow\)\(x(27+30+43)=210500\)
\(\Leftrightarrow\)\(100x=210500\)
\(\Leftrightarrow\)\(x=2105\)
b)\(\Leftrightarrow\)\(x(128-12-16)=5208000\)
\(\Leftrightarrow\)\(100x=5208000\)
\(\Leftrightarrow\)\(x=52080\)
\(x\times27+x\times30+x\times43=210500\)
\(\Leftrightarrow x\times\left(27+30+43\right)=210500\)
\(\Leftrightarrow x\times100=210500\)
\(\Leftrightarrow x=2105\)
X x 27 + X x 30 +X x 43=210500
X x ( 27 + 30 + 43) =210500
X x 100 =210500

X =2105
128 x X - 12 x X -16 x X=5208000
( 128 - 12 - 16 ) x X =5208000
100 x X =5208000

- Nhớ tick cho mình nha
A x 27 + A x 30 + A x 43 =210 500
=> A x ( 27 + 30 + 43 ) = 210 500
=> A x 100 = 210 500
=> A = 210 500 : 100
=> A = 2 105
Vậy A = 2 105
a) \(y\times27+y\times30+y\times43=210500\)
\(y\times\left(27+30+43\right)=210500\)
\(y\times100=210500\)
\(y=210500\div100\)
\(y=2105\)
b) \(15\times y+85\times y=300\)
\(y\times\left(15+85\right)=300\)
\(y\times100=300\)
\(y=300\div100\)
\(y=3\)
\(a,y\times27+y\times30+y\times43=210500\)
\(\Rightarrow y\times\left(27+30+43\right)=210500\)
\(\Rightarrow y\times100=210500\)
\(\Rightarrow y=210500:100=2105\)
\(b,15\times y+85\times y=300\)
\(\Rightarrow y\times\left(15+85\right)=300\)
\(\Rightarrow y\times100=300\)
\(\Rightarrow y=300:100=3\)
\(27x+30x+43x=210500\)
\(100x=210500\)
\(x=210500:100\)
\(x=2105\)
vậy \(x=2105\)
= a x (27 + 30 + 43 )
= a x 100
= 210 500 : 100
= a = 2105
