4 less than 10 times a number = 126

n = 13

Step-by-step explanation:

10n - 4 = 126

Add 4 to both sides.

10n - 4 + (4) = 126 + (4)

10n = 130

Divide both sides by 10.

10n/10 = 130/10

n = 13

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
