1200×17=??
1200 : 24 -( 17 - x )=36
1200 : 24 -( 17 - x )=36
50 -( 17 - x )=36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
1200 : 24 -( 17 - x )=36
50 -( 17 - x )=36
17 - x = 50 - 36
17 - x = 14
x = 17 - 14
x = 3
x=3 em nhé
chuc em hok tt
a) 1200:24-(17-x)=36
a) 1200:24-(17-x)=36
50-(17-x)=36
17-x=50-36
17-x=14
x=17-14
x=3
**** cho mik nhé ^-^
a) 1200 : 24 - ( 17 - x ) = 36
<=> 50 - ( 17 - x ) = 36
<=> 17 - x = 50 - 36
<=> 17 - x = 14
=> x = 17 - 14
Vậy x = 3

tìm x
1200:24-(17-x)=36
Ta có : 1200:24-(17-x)=36
=> 50-(17-x)=36
=>17-x=50-36
=>17-x=14
=>x=17-14=3
50 - (17 - x ) = 36
17 - x = 50-36= 14
x = 17 - 14 = 3
Vậy x = 3
1200:24-(17-x)=36
50-(17-x)=36
17-x=50-36
17-x=14
x=17-14

Câu 1: Tìm x:
a. 1200 x 3 - ( 17 + x ) = 36
1200 × 3 - ( 17 + x) = 36
3600 – (17 + x) = 36
17 + x = 3600 -36
17 + x = 3564
x = 3564 – 17
x = 3547
a. 1200 x 3 - ( 17 + x ) = 36
3600 - ( 17 + x ) = 36
17 + x = 3564
x = 3547
3600 - ( 17 + x ) = 36
17 + x = 3600 - 36
17 + x = 3564
x = 3564 - 17 = 3547
Tính nhanh
14 x 17 = ?
1176 : 28 = ?
24 x 1200 = ?
14768 8750 = ?
\(14\cdot17=14\left(10+7\right)=14\cdot10+14\cdot7=140+98=238\)
\(\dfrac{1176}{28}=42\)
\(24\cdot1200=24\cdot12\cdot100=288\cdot100=28800\)
