k cho mình nha

a) x:0,25+x.11=24

    x.4+x.11     =24

    x.(4+11)     =24

    x.15           =24

                    x=24:15

                    x=1,6

Trả lời :....................

x = 16.................................

Hk tốt,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

a, x :0,25+x.11=24

    x:1/4+x.11=24

    x.4+x.11=24

    x.(4+11)=24

    x.15=24

    x  =24:15

    x=1,6

b, x.8,01-x:100=38

    x.801/100-x.1/100=38

    x.(801/100-1/100)=38

     x.8=34

     x=34:8

     x=4,25

\(2,3:\left(2,8:x\right)=57,5\)

\(2,8:x=\frac{2,3}{57,5}\)

\(2,8:x=0,04\)

\(x=\frac{2,8}{0,04}\)

\(x=70\)

vậy \(x=70\)

\(8,01x-\frac{1}{100}x=38\)

\(8x=38\)

\(x=4,75\)

vậy \(x=4,75\)

k tớ nha Bảo Ngân

 a)

X : 0,25 + X x 11 = 24

<=> X : 1/4 + X x 11 = 24

<=> X x 4 + X x 11 = 24

=> X x ( 4 + 11 ) = 24

=> X x 15 = 24

=> X = 1,6

b)

X x 8,01 - X : 100 = 38

<=> X x 8,01 - X : 1/100 = 38

<=> X x 8,01 - X x 0,01 = 38

=> X x ( 8,01 - 0,01 ) = 38

=> X x 8 = 38

=> x = 4,75
