\bf \cfrac{x}{5}-\cfrac{x}{7}=3\impliedby &#10;\begin{array}{llll}&#10;\textit{let's multiply both sides by }\stackrel{LCD}{35}\\&#10;\textit{to do away with the denominators}&#10;\end{array}&#10;\\\\\\&#10;35\left( \cfrac{x}{5}-\cfrac{x}{7}\right)=35(3)\implies 7x-5x=105&#10;\\\\\\&#10;2x=105\implies x=\cfrac{105}{2}

Find the distance between the two points rounding to the nearest tenth (if necessary).
Genrish500 [490]

Answer:

13 units

Step-by-step explanation:

(-1,5) and (4, -7)

To find the distance of two points, we use the distance formula:

d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }

Let's plug in what we know.

d = \sqrt{(4 - (-1))^2 + (-7 - 5)^2 }

Evaluate the double negative.

d = \sqrt{(4 +1))^2 + (-7 - 5)^2 }

Evaluate the parentheses.

d = \sqrt{(5)^2 + (-12)^2 }

Evaluate the exponents.

d = \sqrt{(25) + (144) }

Add.

d = \sqrt{(169) }

Evaluate the square root.

d = 13

13 units

Hope this helps!
