Question

a) X : 0,25 + X × 11 = 24                       b) X × 8,01 – X : 100 = 38

c) 2,3 : 2,8 × X = 57,5                            d) 0,16 : (X : 3,5) = 2,8

Answer 1

đúng như trên đấy nhé Hưng:)))

Answer 2

a) \(x:0,25+x\cdot11=24\)

\(x\left(4+11\right)=24\)

\(x=\frac{8}{5}\)

b) \(x\cdot8,01-x:100=38\)

\(x\left(8,01-0,01\right)=38\)

\(x=\frac{19}{4}\)

c) \(2,3:2,8\cdot x=57,5\)

\(\frac{23}{28}\cdot x=57,5\)

\(x=70\)

d) \(0,16:\left(x:3,5\right)=2,8\)

\(x:3,5=\frac{2}{35}\)

\(x=\frac{1}{5}\)

Answer 3

a)\(x:\frac{1}{4}+x.11=24\)

   \(x.4+x.11=24\)

   \(x.15=24\)

    \(x=\frac{24}{15}\)

b)\(2,3:2,8.x=57,5\)

   \(\frac{23}{28}.x=57,5\)

     \(x=70\)

Answer 4

đúng quá chuẩn
