a) x= 2.3
b)x=9.225
c)x= 2.4
d)x= 2.5
đúng 100% luôn bạn ak
a) 60,36 : x + 43,14 : x = 45
(60,36 + 43,14) : x = 45
103,5 : x = 45
x = 103,5: 45
x = 2,3
b) 12,3 : x x 4,5 = 6
x x 4,5 = 12,3 : 6
x x 4,5 = 2,05
x = 2,05 : 4,5
x = 41/90
c) x x 4 x 3,75 = 36
x x 15 = 36
x = 36 : 15
x = 2,4
d) 135 : x : 12 = 4,5
x : 12 = 135 : 4,5
x : 12 = 30
x = 30 x 12
x = 360
tớ nhah nhất , ủng hộ nha
a) (60.36+43.14):x=45
103.5:x=45
x=103.5:45
x=2.3
b)12.3:xx4.5=6
12.3:x=6:4.5
12.3:x=\(\frac{4}{3}\)
x= 12.3: \(\frac{4}{3}\)
x=9.225
c)X x4x3.75=36
x=36:3.75:4
x=2.4
d)135:x:12=4.5
135:X=4.5x12
135:x=54
