tim x biet (x-32):16=48
tim x biet x-32 chia 16=48 x=
X =
tim x,biet
1) 135 +(121-x) = 231
2) x - 32 chia 16 = 48
135 + ( 121 - x ) = 231
121 - x = 231 - 135
121 - x = 96
x = 121 - 96
x = 25
x - 32 : 16 = 48
x- 2 = 48
x= 48 + 2
x = 50
Tim x biet :
c ) - ( x + 48 ) + 213 = -16
- (x + 48) + 213 = -16
- (x + 48) = -16 - 213
- (x + 48) = -229
=> x + 48 = 229
=> x = 229 - 48
=> x = 181
-(x+48)+213=-16
-x-48=-16-213
-x-48=-229
-x=-229+48
-x=-181
x=181
Nhớ tk phát nhé.
-(x+48)+213=-16
-(x+48) =-16+(-213)
-x-48 =-229
-48+229 =x
\(\Rightarrow\)x =181
tim so tu nhien x biet:7/9+16/48<x<43/8+0.125
ta có: 10/9 < x < 11/2
=> 1 < x < = 5
=> x = {2;3;4;5}
\(\frac{7}{9}+\frac{16}{48}< x< \frac{43}{8}+0.125\)
\(\frac{10}{9}< x< \frac{11}{2}\)
\(1.11< x< 5.5\)
Vậy \(x=2;3;4;5.\)
Ta có:7/9+16/48=7/9+1/3=10/9
43/8+0.125=43/8+1/8=11/2
=>10/9<x<11/2
=>9/9<10/9<x<11/2<12/2
=>1<x<6
Vì x là số tự nhiên nên x=2,3,4,5
Vậy x=2,3,4,5.
tim cac so tu nhien x biet :
a) 48 + 288 : ( x -3) = 50
b) 2x . 16 =128
a, 48 + 288 : ( x - 3 ) = 50
288 : ( x - 3 ) = 50 - 48
288 : ( x - 3 ) = 2
x - 3 = 288 : 2
x - 3 = 144
x = 144 + 3
x = 147
b, \(2^x\) . 16 = 128
\(2^x\) = 128 : 16
\(2^x\) = 8
\(2^x\) = \(2^3\)
=> x = 3
48 + 288 : ( x - 3 ) = 50
288 : ( x - 3 ) = 50 - 48
288 : ( x - 3 ) = 2
( x - 3 ) = 288 : 2
x - 3 = 144
x = 144 + 3
x = 147
2^x . 16 = 128
2^x . 2^4 = 2^7
2^x = 2^7 : 2^4
2^x = 2^3
x = 3
(x-32):16=48
và x-32:16=48
giúp tớ với
(x-32):16=48
=> x-32=48.16
=> x-32=768
=> x=768+32
=> x=800
x-32:16=48
=> x-2=48
=> x=48+2
=> x=50
( x - 32 ) : 16 = 48
x - 32 = 48 . 16
x - 32 = 768
x = 768 + 32= 800
x - 32 : 16= 48
x - 2 = 48
x = 48 + 2= 50
dễ thui màk:
( x - 32 ) : 16 = 48
x - 32 = 48 . 16
x - 32 = 768
x = 768 + 32
x = 800
x - 32 : 16 = 48
x - 2 = 48
x = 48 + 2
x = 50
tim x:
a) 5x-32=48
b)215-(2x+143)=16
c)31-5x=102
giup em voi
a ) 5x - 32 = 48
5x = 48 + 32
5x = 80
x = 80 : 5
x = 16
b ) 215 - ( 2x + 143 ) = 16
( 2x + 143 ) = 215 - 16
( 2x + 143 ) = 199
2x = 199 -143
2x = 56
x = 56 : 2
x = 28
