Question

a) 1237,9: (37,2 + 62,8) - 5,6 ?

b) x + 8,3 = 12,03 * 4 ?

Answer 1

`a)`

`1237,9: (37,2 + 62,8) - 5,6`

`=1237,9:100-5,6`

`=12,379-5,6`

`=6,779`

`b)`

`x+8,3=12,03xx4`

`x+8,3=48,12`

`x=48,12-8,3`

`x=39,82`

Vậy `x=39,82`

Answer 2

a) 1237,9: (37,2 + 62,8) - 5,6 ?

= 1237,9 : 100 - 5,6

= 12,379 - 5,6

=6,779

b) x + 8,3 = 12,03 x 4

x + 8,3 = 48,12

x          = 48,12 - 8,3

x          = 39,82

 

Answer 3

6.779

39/82

Answer 4

\(a,1237,9:\left(37,2+62,8\right)-5,6\)

\(=1237,9:100-5,6\)

\(=12,379-5,6\)

\(=6,779\)

\(b,x+8,3=12,03\times4\)

\(\Leftrightarrow x+8,3=48,12\)

\(\Leftrightarrow x=48,12-8,3\)

\(\Leftrightarrow x=39,82\)
