`6,25 : 0,25 + 6,25 xx 7 - 6,25`
`= 6,25 : 1/4 + 6,25 xx7-6,25 xx1`
`=6,25 xx 4 + 6,25xx7-6,25xx1`
`=6,25 xx (4+7-1)`
`=6,25 xx10`
`=62,5`.

6,25 X 8 + 6,25 : 0,5
= 6,25 x 8 + 6,25 x 2
= 6,25 x ( 8 + 2)
= 6,25 x 10
= 62,5

\(x\div4,5=6\) \(6,25\times x+3,75\times x=30\)
\(x=6\times4,5\) \(x\times\left(6,25+3,75\right)=30\)
\(x=27\) \(x\times10=30\)
\(x=30\div10\)
\(x=3\)
a,
\(x:4,5=6\)
\(x=6\times4,5\)
\(x=27\)
b,
6,25 \(\times\) \(x\) + 3,75\(\times\)\(x\) = 30
\(x\) \(\times\)(6,25 + 3,75) = 30
\(x\) \(\times\) 10 = 30
\(x=30:10\)
\(x=3\)

X x 2 + X x 0,5 = 6,25
X x ( 2 + 0,5 ) = 6,25
X x 2,5 = 6,25
X = 6,25 : 2,5
X = 2,5
X x (2+0,5) = 6,25
X x 2,5 = 6,25
X = 6,25 : 2,5 = 2,5
k mk nha

Lời giải:
$6,25\times x+x+x\times 3,75=49,36$
$x\times (6,25+1+3,75)=49,36$
$x\times 11=49,36$
$x=49,36:11=4,49$

X x 2 + X x 0,5 = 6,25
X x (2 + 0,5) = 6,25
X x 2,5 = 6,25
X = 6,25 : 2,5
X = 2,5
Nhớ k cho mình nhé
\(x\cdot2+x\cdot0,5=6,25\)
\(x\cdot\left(2+0,5\right)=6,25\)
\(x\cdot2,5=6,25\)
\(x=6,25:2,5=2,5\)

6,25 : 0,125 - 6,25 : 0,25 + 100
= ( 6,25 x 8 ) - ( 6,25 x 4 ) + 100
= 50 - 25 + 100
= 25 + 100
= 125

Chúc bạn học tốt
6,25x2+6,25x25%+6,25+6,25x75/100+6,25x6
=6,25x2+6,25x0,25+6,25+6,25x0,75+6,25x6
=6,25(2+0,25+1+0,75+6)
=6,25x10=62,5
