a)437+(248-x)=635
248-x=635-437=198
x=248-198=50
b)5.(x+27)=465
x+27=465/5=93
x=93-27=66
c)3.(x+3)=30
x+3=30:3=10
x=10-3=7
d)8x-9=31
8x=31-9=22
x=22/8=11/4
e)7x-9=26
7x=26+9=35
x=35:7=5
g)76-3.(x+5)=16
3.(x+5)=76-16=60
x+5=60/3=20
x=15

1/3x + 3/4x - 75% = -5 1/4
=> x - 3/4 = -21/4
=> x = -21/4 + 3/4
=> x = -9/2
60%x + 5/6x = -76
=> 3/5x + 5/6x = -76
=> 43/30x = -76
=> x = -76 : 43/30
=> x = -2280/43
\(\frac{1}{3}x+\frac{3}{4}x-75\%=-5\frac{1}{4}\)
\(\frac{13}{12}x-\frac{3}{4}=-\frac{21}{4}\)
\(\frac{13}{12}x=-\frac{9}{2}\)
\(x=-\frac{54}{13}\)
\(60\%.x+\frac{2}{3}x=-76\)
\(\frac{3}{5}x+\frac{2}{3}x=-76\)
\(\frac{19}{15}x=-76\)
\(x=-60\)

\(\frac{3}{4}\)của 76 là: 76: 4x 3= 57
Vậy \(\frac{3}{4}\)của 76 là 57.

a)
\(25+|x-1|=\left(-15\right)+76\)
\(\Rightarrow25+|x-1|=61\)
\(\Rightarrow|x-1|=61-25\)
\(\Rightarrow|x-1|=36\)
\(\Rightarrow\orbr{\begin{cases}x-1=36\\x-1=-36\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=36+1\\x=-36+1\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=37\\x=-35\end{cases}}\)
Vậy \(x=37\) hoặc \(x=-35\)
a, 25 + / x - 1 / = ( - 15 ) + 76
25 + / x - 1 / = 61
/ x - 1 / = 61 - 25
Tự tính nốt

Chữ số tận cùng của:
a) A = 0
b) B = 8
c) C = 4
Mk ko chắc đâu! Mk nghĩ thế, ko bik đúng hay sai.

a) -1,6: (1+2/3)-76/25 =
-1,6:5/3-76/25=
-24/25-76/25=-100/25=-4
b) -3+1/5 . 5/64 + (0,8-(2+4/15)) : 11/3=
-16/5.5/64+(12/15-34/15):11/3=
-1/4+(-22/15):11/3=
-1/4+(-2/5)=
3/20
tick cho mình nha các bạn
3/4 của 76 cm là: 76 . 3/4 = 57cm
