A=\(3\frac{1}{8}.3,2-\frac{50}{100}\)+(-1/2)²:1/4

A=25/8.16/5-1/2+1/4:1/4

A=10-1/2+1

A=11-1/2=21/2

z x 3 = 35 x ( z - 1 )

z x 3 = 35z - 35

35z - z = 3 + 35

34z = 38

z = 38/35

\(\frac{S}{2}=2+\frac{1}{6}+\frac{1}{12}+.....+\frac{1}{90}\)

\(\Rightarrow\frac{S}{2}=2+\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{4}+.....+\frac{1}{9}-\frac{1}{10}\)

\(\Rightarrow\frac{S}{2}=2+\frac{1}{2}-\frac{1}{10}\)

\(\Rightarrow\frac{S}{2}=2+\frac{2}{5}=\frac{12}{5}\)

\(\Rightarrow\frac{S}{2}=\frac{6}{5}< 2\)

=> S<2

1. she/ know a lot about cooking

=> She knows a lots about cooking

2. we/ make dinner at the weekends

=> She makes dinner at the weekend

3.i/not/leave work on time very often

4. she/ meet her brother every week?

=> Does she meet her brother every weekend ?

5.they/ find London's weather cold

\(a.\frac{4}{5}\times\frac{3}{x}\times\frac{2}{11}=\frac{24}{165}\)

\(\frac{3}{x}=\frac{24}{165}:\frac{4}{5}:\frac{2}{11}\)

\(\frac{3}{x}=1\)

\(\Rightarrow x=3\)

\(b.\frac{4}{3}:\frac{x}{5}=\frac{5}{13}\times\frac{4}{9}\)

\(\frac{4}{3}\times\frac{5}{x}=\frac{20}{117}\)

\(\frac{5}{x}=\frac{20}{117}:\frac{4}{3}\)

\(\frac{5}{x}=\frac{5}{39}\)

\(\Rightarrow x=39\)

Đúng nha

\(\frac{x^2}{\sqrt{5}}-\sqrt{20}=0\)

\(\Rightarrow\frac{1}{\sqrt{5}}\left(x^2-10\right)=0\)

\(\Rightarrow x^2=10\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=\sqrt{10}\\x=-\sqrt{10}\end{array}\right.\)
