One point on a line is given the coordinate 5.3. a second point on the line has a coordinate of 8.7.
the distance between these points is units.

3.2

Step-by-step explanation:

The distance formula  on a number line is

d= x2-x1

d= 8.7-5.3 =3.2

The distance between these points is 5 units.

Step-by-step explanation:

We know that by Distance formula , the distance between two points (a,b) and (c,d) is given by :-

The given points = (5,3) and (8,7)

The distance between theses points will be :

Since , Distance is always positive , it means the distance between the given points is 5 units.

12 servings. 4 times 3= 12

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
