60,50 - 45,69 - 5,50

= 60,50 - 5,50 - 45,69

= 55 - 45,69

= 9,31

k nha

60,50 - 45,69 - 5,50

= (60,50 - 5,50) - 45,69

= 55 - 45,69

= 9,31

k mình nha

Mình cảm ơn các bạn nhiều

9,31 nha

60,50 - 50,65 - 2,50

= (60,50 - 2,50) - 50,65

= 58 - 50,65

= 7,35

60,50 - 50,65 - 2,50

=(60,50 - 2,50) - 50,65

= 58 - 50,65

= 7,35

k mình nha

Mình cảm ơn các bạn nhiều

Thank you very much

(^_^)

Giải:

60,50 - 50,65 - 2,50

= 9,85 - 2,50

= 7,35

20,50 - 18,54 - 1,50

= (20,50 - 1,50) - 18,54

= 19 - 18,54

= 0,46

k mình nha

Mình đang cần điểm hỏi đáp

  20,50 - 18,54 - 1,50

= ( 20,50 - 1,50 ) - 18,54

= 19 - 18,54

=     0,46

9,2 đúng100% .

đổi 1.26dm=12.6cm

chiều cao là:57.96*2:12.6=9.2

k minh nha

lay ba to

\(92,6-\left(x+25,8\right)=37,04\)

\(\Rightarrow x+25,8=92,6-37,04\)

\(\Rightarrow x+25,8=55,56\)

\(\Rightarrow x=55,56-25,8=29,76\)

\(92,6-\left(x+25,8\right)=37,04\)

\(\Rightarrow92,6-x-25,8=37,04\)

\(\Rightarrow66,8-x=37,04\)

\(\Rightarrow66,8-37,04=x\)

\(\Rightarrow x=29,76\)
