b) 1,44:x=0,12
c)2(3x-3,7)=5,2
VA ROG DAU CORANA!!!!!!!!!!!!!
DAU 100 DE PUNCTE ​

Answer 1

Răspuns:

Explicație pas cu pas:

b. x = 1,44/0,12 => x - 144/100 : 100/12 => x = 144/100 x 100/ 12

= 144/12 = 12

c.6x - 7,4 = 5,2 => 6x = 12,6 => x = 12.6/6 = 2,1

Answer 2

$\it a)\ 37,5+14,07-x=17,03 \Rightarrow 51,57-x=17,03 \Rightarrow x=51,57-17,03\\ \\ b)\ 1,44:x=0,12 \Rightarrow x=1,44:0,12 \Rightarrow x=144:12 \Rightarrow x=12\\ \\ c)\ 2(3x-3,7)=5,2|_{:2} \Rightarrow 3x-3,7=2,6 \Rightarrow 3x=2,6+3,7\Rightarrow 3x=6,3$
