Question

_{(75 : 3 + 2 . 9^2) : x = 11}

_{Giúp ạ}

 

Answer 1

\(\left(75:3+2.9^2\right):x=11\)
\(\left(25+2.81\right):x=11\)
\(\left(25+162\right):x=11\)
\(187:x=11\)
\(x=187:11\)
\(x=17\)

Answer 2

TL : 

(75:3 + 2.9^2):x = 11

(25 + 162):x = 11

187:x = 11

x = 187: 11

x = 17.

Answer 3

(75:3+2.9²):x=11

(25+2.81):x=11

(25+162):x=11

187:x=11

x=187:11

x=17

Answer 4

Answer 5

(75:3+2.9²):x=11

(75:3+2.81):x=11

    (25+162):x=11

           187:x=11

                  x=187:11

                  x=17
