If x-2y=10 and x≠0, what is the value of 2x/y+5

VladimirAG [237]

Answer: 4

Step-by-step explanation:

x - 2y =10

x = 10 + 2y

$\frac{2x)}{y + 5}$

$\frac{2(10+2y)}{y+5}$

$\frac{20+4y}{y+5}$

$\frac{4(5+y)}{y+5}$ ... cancel like terms (y + 5)

Answer:

$d=\sqrt{2,537}\ m$ or $d=50.37\ m$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points in three dimensions is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}+(z2-z1)^{2}}$

Let

$A(5,3,1)$ -----> coordinates of the barrel of her gun

$B(38,41,3)$ -----> coordinates of the target

substitute the values

$d=\sqrt{(41-3)^{2}+(38-5)^{2}+(3-1)^{2}}$

$d=\sqrt{(38)^{2}+(33)^{2}+(2)^{2}}$

$d=\sqrt{1,444+1,089+4}$

$d=\sqrt{2,537}\ m$

$d=50.37\ m$
