7000 + 2000 = 9000
16000 : 2 = 8000
9000 - 3000 = 6000
8000 x 3 = 24 000
8000 : 2 = 4000
11000 x 3 = 33 000
3000 x 2 = 6000
49000 : 7 = 7000
7000 + 2000 = 9000
16000 : 2 = 8000

\(\text{X x 46 - X x 24 = 88 x 25 }\)
\(x.\left(46-24\right)=2200\)
\(x.22=2200\)
\(x=2200:22\)
\(x=100\)
học tốt
\(x.46-x.24=88.25\)
\(\Rightarrow x.\left(46-24\right)=2200\)
\(\Rightarrow x.22=2200\)
\(\Rightarrow x=100\)
hok tốt
3000 : 10 x 500 = 300 x 500 = 150000
2000 : 100 x 600 = 20 x 600 = 12000
( x + 1 ) + ( x + 3 ) + ( x + 5 ) + ... + ( x + 15 ) = 88
=> x + 1 + x + 3 + x + 5 + ... + x + 15 = 88
=> x . ( 1 + 3 + 5 + ... + 15 ) = 88
=> x . 64 = 88
=> x = 88 : 64
=> x = 1,375
Dãy trên có số số x là :
( 15 - 5 ) : 2 + 1 = 8 (số )
x . 8 + ( 1 + 3 + ... + 15 ) = 88
Tổng của dãy 1 + 3 + .. + 15 là :
( 15 + 1 ) x 8 : 2 = 64
x . 6 + 64 = 88
x . 6 = 88 - 64
x . 6 = 24
x = 24 : 6
x = 4
Hướng dẫn giải:
a) 3000 + 13000 – 6000 = 10000
b) 3000 x 4 = 12000
c) 25000 : 5 = 5000
d) 2000 x 3 : 2 = 3000.
ok
\(x\times13+x\times88-x=3000\)
\(x\times\left(13+88-1\right)=3000\)
\(x\times100=3000\)
\(x=3000:100\)
\(x=30\)
