x=15 vì:
5(24+x)=3(50+x)
120+5x=150+3x
2x=130
\(\frac{24+x}{50+x}=\frac{3}{5}\)
Ta có : ( 24 + x ) * 5 = ( 50 + x ) * 3
24 * 5 + x * 5 = 50 * 3 + x * 3
120 + x * 5 = 150 + x * 3
x * 5 - x * 3 = 150 - 120
x * 2 = 30
x = 30 / 2
x = 15 k mk nha~~

\(\frac{24+x}{50+x}=\frac{3}{5}\)
\(\frac{24+x}{50+x}\)=\(\frac{3}{5}\)
\(\frac{24+x}{50+x}\)=\(\frac{3}{5}\)
\(\frac{24+x}{50+x}\)= \(\frac{3}{5}\)
\(\frac{24+x}{50+x}\)= \(\frac{3}{5}\)
\(\frac{24+x}{50+x}\)= \(\frac{3}{5}\)
tìm x
\(\left(x+\frac{1}{2\cdot4}\right)+\left(x+\frac{1}{4\cdot6}\right)+\left(x+\frac{1}{6\cdot8}\right)+\left(x+\frac{1}{8\cdot10}\right)+\left(x+\frac{1}{10\cdot12}\right)=50\frac{5}{24}\)
Tìm x: \(\frac{24+x}{50+x}\)= \(\frac{3}{5}\)
Đang cần gấp đúng tik, kết bạn luôn!
Tìm kết quả \(\frac{24}{400}+50\%+\)\(\frac{3}{100}+25\%\)
Tìm m \(\frac{2}{5}\)x m +25% x m + m = 16, 5
Trình bày hộ mình nha !!
