hâm tự trả lời cho chính mình

50 + 50 + 50 + 50 + 60 + 60 - 20

= 300

nha bn

_mk k bn r`_

50+50+80+20+60+55+44+1+40=400 nha

\(50+50+80+20+60+55+44+1+40\)

\(=\left(50+50\right)+\left(80+20\right)+\left(60+40\right)+\left(55+44+1\right)\)

\(=100+100+100+100\)

\(=100.4\)

\(=400\)

ok 

ko ghi lại đề 

= ( 50 + 50 ) + ( 80 + 20 ) + ( 60 + 40 ) + ( 55 + 44 + 1 ) 

=      100              100              100             100

=    100 x 4 

= 400

\(60+40+50+50+40+5+95+50+10\)

\(=\left(60+40\right)+\left(50+50\right)+\left(40+50+10\right)+\left(95+5\right)\)

\(=100+100+100+100\)

\(=100.4\)

\(=400\)

nho gui tin nhan do

60 + 40  + 50 + 50 + 40 + 5 + 95 + 50 + 10

= 100 + 100 + 45 + 145 + 10

= 200 + 200

= 400

chúc bạn học tốt ^ _ ^

x+60=100

    x= 100-60

    x= 40

x+50=50

    x= 50-50

    x=0

tk nhé

số x đó là

x+60=100

x=100-60

x=40

x+50=50

x=50-50

x=0

nhe sbn

k mik nha

\(50+60+40+50+50+45\)

\(=\left(50+50\right)+\left(60+40\right)+\left(45+55\right)\)

\(=100+100+100\)

\(=100.3\)

\(=300\)

the lun

50+60+40+50+45

=(50+50)+(60+40)+45
