Ta có : \(a+a+a+\frac{1}{2}.\frac{2}{5}+a+\frac{8}{10}+a=136\)
\(\Leftrightarrow5a+\frac{1}{2}.\frac{2}{5}+\frac{8}{10}=136\)
\(\Leftrightarrow5a+\frac{1}{5}+\frac{8}{10}=136\)
\(\Leftrightarrow5a+1=136\)
\(\Leftrightarrow5a=135\)
\(\Leftrightarrow a=27\)
Vậy \(a=27\)
a + a + a + 1/2 . 2/5 + a + 8/10 + a = 136
=> a + a + a + a + a + 1/2 . 2/5 + 4/5 = 136
=> 5a + 1/5 + 4/5 = 136
=> 5a + 1 = 136
=> 5a = 136 - 1
=> 5a = 135
=> a = 135 : 5
=> a = 27
\(a+a+a+\frac{1}{2}\times\frac{2}{5}+a+\frac{8}{10}=136\)
\(\Leftrightarrow5a+\frac{1}{2}\times\frac{2}{5}+\frac{8}{10}=136\)
\(\Leftrightarrow5a+1=136\)
\(\Leftrightarrow5a=135\)
\(\Leftrightarrow a=27\)
a + a + a +1/2 * 2/5 + a +8/10 + a = 136
5a + 1/2 . 2/5 + 8/10 = 136
5a + 1/5 + 8/10 =
136
5a + 1 = 136
5a = 136 -1
5a = 135
a = 135 : 5
a = 27
Đây là avatar của mình nè
bang 136 nha ban
gdggfgrdyjtuiyfbvxev
con khoong bieets nha coo
a + a + a + 1/2 * 2/5 + a + 8/10 + a = 136
\(\Leftrightarrow\)5a + 1 = 136
\(\Rightarrow\)a = 27
a+a+a+1/2*2/5+a+8/10+a=136
a+a+a+2/10+a+8/10+a=136
a+a+a+a+a+2/10+8/10=136
5a+1=136
5a=136-1
5a=135
a=135:5
a=27
ta có:a+a+a+1/2.2/5+a+8/10+a=136
5a+1/2.+2/5=136
5a+1/5+8/10=136
5a+1=136
5a=135
a=27
Vậy a=27
