=(1,8+1,2)+(0,66+0,34)=3+1=4

=6,48 x (1125-112 -13)=6,48 x 1000= 6480

=4,8 x ( 24,5 +15,6)=4,8 x 40,1 =192,48

(4,8×95)+(9,6×2)+4,8=480

(4,8 × 95) + (9,6 × 2) + 4,8=480

bọn điên này tính nhanh cơ mà

\(\frac{-5}{1,2}=\frac{x}{-4,8}=>-5.-4,8=1,2.x\)

=> 24 = 1,2x

=> 24 : 1,2 = x

=> 20 = x

\(\left(\frac{x}{5}\right)^2=\frac{9}{25}=>\left(\frac{x}{5}\right)^2=\left(\frac{3}{5}\right)^2\)

=> \(\frac{x}{5}=\frac{3}{5}=>x=3\)

đúng 100%

24 : x - 1,2 =4,8

24:x=4,8+1,2

24:x=6

x=24:6

x=4

X x 3,6 + X x 6,4 = 9,5

X x (3,6+6,4)=9,5

X x 10=9,5

X=9,5:10

X=0,95

= 4,8 ( 13,5 + 5,5 + 1 )

= 4,8 x 20

= 96

=4,8x13,5+5,5x48+4,8x1

=4,8x(13,5+5,5+1)

=4,8x20

=96

\(4,8\times13,5+5,5\times4,8+4,8\)

\(=4,8\times13,5+5,5\times4,8+4,8\times1\)

\(=4,8\times\left(13,5+5,5+1\right)\)

\(=4,8\times20\)

\(=96\)

4,8×13,5-2,5×4,8-4,8

=4,8×13,5-2,5×4,8-4,8×1

=4,8×(13,5-2,5-1)

=4,8×10

=48

4.8 x 13.5 - 2.5 x 4.8 - 4.8

 = 4.8 x ( 13.5 - 2.5 - 1 )

= 4.8 x 10

= 48

\(4,8\times13,5-2,5\times4,8-4,8\)

\(=4,8\times\left(13,5-2,5-1\right)\)

\(=4,8\times10\)

\(=48\)

_Chúc bạn học tốt_

4,8 x 13,5 - 2,5 x 4,8 – 4,8 

= 4,8 x (13,5 - 2,5 -1)

= 4,8 x 10 = 48

\(a,x\times4,8+5,2\times x=160\\ x\times\left(4,8+5,2\right)=160\\ \Rightarrow x\times10=160\\ \Rightarrow x=16\)

a. \(x\text{×}4,8+5,2\text{×}x=160\)

\(x\text{×}\left(4,8+5,2\right)=160\)

\(x\text{×}10=160\)

\(x=160:10=16\)
