tìm X
Tính thuận tiện:
435 x 16 + 565 x 17
\(435\times16+565\times17\)
\(=435\times16+565\times\left(16+1\right)\)
\(=435\times16+565\times16+565\)
\(=16\times\left(435+565\right)+565\)
\(=16\times1000+565\)
\(=16000+565\)
\(=16565\)
565-13.x=370
565 - 13x = 370
13x = 565 - 370 = 195
x = 195 : 13
x = 15
\(565-13x=370\\ 13x=195\\ x=195:13\Rightarrow x=15\)
565-13-x=370
tìm x, biết:
a.565-13.x=370
b.105-(135-7x):9=97
a) 565 - 13.x = 370
13.x = 565 - 370
13.x = 195
x = 195 : 13
x = 15
b) 105 - (135 - 7x) : 9 = 97
(135 - 7x) : 9 = 105 - 97
(135 - 7x) : 9 = 8
135 - 7x = 8 x 9
135 - 7x = 72
7x = 135 - 72
7x = 63
x = 63 : 7
x = 9
a) 565 - 13.x = 370
13.x = 565 - 370
13.x = 195
x = 195 : 13
x = 15
b) 105 - (135 - 7x) : 9 = 97
(135 - 7x) : 9 = 105 - 97
(135 - 7x) : 9 = 8
135 - 7x = 8 x 9
135 - 7x = 72
7x = 135 - 72
7x = 63
x = 63 : 7
x = 9
cho like
a) 565 - 13.x = 370
13x = 565 - 370
13x = 195
x = 195 : 13
x = 15
b) 105 - (135 - 7x) : 9 = 97
(135 - 7x) : 9 = 105 - 97
(135 - 7x) : 9 = 8
135 - 7x = 8.9
135 - 7x = 72
7x = 135 - 72
7x = 63
x = 63 : 7
x = 9
565+x=566
bujk
\(565+x=566\)
\(x=566-565\)
\(x=1\)
\(k.nha\)
\(565+x=566\)
\(x=566-565\)
\(x=1\)
hok tốt
