pk

=> không biết
Uung ho nha
x + 200 + 300 - 100 = 900
x + 400 = 900
x = 900 - 400
x = 500
tk mk nha mk sẽ tk lại
x + 200 + 300 - 100 = 900
x + 500 - 100 = 900
x + 400 = 900
x = 900 - 400

900 + 100 + 200 - 200 + 14 x 2 =?
12 x 3 =?
tick mk , mk tick lại !
90+100+300-200+14x2=318
12x3=36
ai k mình mình k lại cho
900 + 100 + 200 - 200 + 14 x 2 =?
12 x 3 =?
tick mk , mk tick lại !
900 + 100 + 200 - 200 + 14 x 2
= 900 + 100 + 200 - 200 + 28
= 2028
12 x 3 = 36
k mk nhé bn iu ^_-
900 + 100 + 200 - 200 + 14 x 2
= 900 + 100 + 200 - 200 + 28
= 900 + 100 + 0 + 28
= 1000 + 28
= 1028
12 x 3 = 36
\(900+100+200-200+14x2\)
\(=900+100+200-200+28\)
\(=1000+200-200+28\)
\(=1200-200+28\)
\(=1000+28\)
\(=1028\)
K nha mình sẽ k bạn hứa luôn!
