the value of x such that 7x^3 - |-35| = 13 . 182
Find the value of x such that . x - y = 13; 3/10x = 9/4y
Answer: x = ?
dễ thôi mà \(\frac{3}{10}x=\frac{9}{4}y\Rightarrow\)\(\frac{9}{30}x=\frac{9}{4}y\)
\(\Rightarrow4x=30y\)(x là 30 phần ; y là 4 phần)
Áp dụng lại dạng toán tổng-hiệu của lớp 4
Hiệu số phần bằng nhau là :
30 - 4 = 26 (phần)
Vậy x =
\(\frac{13}{26}\cdot30=\frac{1}{2}\cdot30=15\)
