Tìm x biết:
3.x/2.5+3.x/5.8+3.x/8.11+3.x/11.14=1/21
tìm x; 3.x/2.5 + 3.x/5.8 + 3.x/8.11 + 3.x/11.14= 1/21
làm giúp mình với nha, mình đang cần gấp lắm
Tìm x:
3.x/2.5+3.x/5.8+3.x/8.11+3.x/11.14+3.x/14.17= hỗn số âm 1 ba phần 5
tìm x biết 3x/2.5+3x/5.8+3x/8.11+3x/11.14 = 1/21
3.x/2.5+3.x/5.8+3.x/8.11+3.x/11.4=1/21
Tìm x biết: \(\dfrac{3x}{2.5}+\dfrac{3x}{5.8}+\dfrac{3x}{8.11}+\dfrac{3x}{11.14}=\dfrac{1}{21}\)
1.Tìm x:
3x/2.5 + 3x/5.8 + 3x/8.11 +3x/11.14 =1/21
B=3/2.5+3/5.8+3/8.11+3/11.14
1/5.8+1/8.11+1/11.14+...+1/x(x+3)=27/480
