Answer:

\boxed{x=\dfrac{121}{2}\to x=60.5}

Step-by-step explanation:

\dfrac{3}{6}=\dfrac{x}{121}\qquad\text{simplify}\ \dfrac{3}{6}=\dfrac{3:3}{6:3}=\dfrac{1}{2}\\\\\dfrac{1}{2}=\dfrac{x}{121}\qquad\text{cross multiply}\\\\2x=121\qquad\text{divide both sides by 2}\\\\x=\dfrac{121}{2}

Answer:

60.5 =x

Step-by-step explanation:

3/6 = x/121

We can use cross products

3*121 = 6*x

363 = 6x

Divide by 6

363/6 = 6x/6

60.5 =x

Please help me find the distance between the points (5,4) and (1,-2) and express the answer in simplest radical form.
finlep [7]
The distance between two points can be calculated using the following formula:
distance = sqrt [ (x2-x1)^2 + (y2-y1)^2]

Now, we are given the two points (5,4) and (1,-2)
Substitute with the given points in the above equation to get the distance as follows:
distance = sqrt [(1-5)^2 + (-2-4)^2]
distance = sqrt [16+36] = sqrt[52]
distance = 2√13 = 7.2111 units
