Answer:

Imagine that the number that we are looking for is x

We know that:

x/5 - 78 = 9

x/5 = 9 + 78

x/5 = 87

x = 87 . 5 = 435

So the number we need is 435

What is the distance between (1,-5) and (-3,6)

Wewaii [24]

Answer:

$\large\boxed{\sqrt{137}\approx11.7}$

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have two points (1, -5) and (-3, 6). substitute:

$d=\sqrt{(-3-1)^2+(6-(-5))^2}=\sqrt{(-4)^2+11^2}=\sqrt{16+121}=\sqrt{137}$

Find The distance between (-3,1) and (-1,6). If necessary,round to the nearest tenth.

kifflom [539]

Use distance formula:-

distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]

let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.
