Find the smallest value of x such that: 2x+3>5
find the value of n such that the polynomial 2x^5 - 3x^3 + x^2 +n is divisible by the polynomial x+2
tìm giá trị của n sao cho đa thức 2x ^ 5 - 3x ^ 3 + x ^ 2 + n chia hết cho đa thức x + 2
Find the value of x such that:\(\frac{3}{2x+7}=\frac{5}{3x+9}\)
\(x\ne-\frac{7}{2};x\ne-3\)
\(\Rightarrow3\left(3x+9\right)=5\left(2x+7\right)\)
\(\Rightarrow9x+27=10x+35\)
\(\Rightarrow10x-9x=27-35\)
\(\Rightarrow x=-8\)
Find the smallest integer value of x such that: 2x+3>5
Find the value of x such that A=\(\frac{5x^2-8x+8}{2x^2}\) reaches the minimun value.
Find the value of x such that: \(\frac{5}{7-2x}=\frac{3}{x-3}\)
find the value of a such that 2/3<a/9<5/6
Toán tiếng anh 5 à ,
a = 7
cách làm , ta quy đồng mẫu , lấy mẫu số chung nhỏ nhất là 18 :
2 / 3 = 12 / 18
5 / 6 = 15 / 18
a / 9 = a x 2 / 18
13 không thể là a x 2 vì không chia hết cho 2 nên a x 2 = 14
a = 14 : 2
a = 7
Find the value of such that
