Evaluate the expression when c=3 and d=25.
d- 5c

10

Step-by-step explanation:

d-5c=25-5(3)

=25-15

=10

10

Step-by-step explanation:

C =3 and D =25 in the expression D - 5C

25 - 5C

25 - 5 x 3 so then 5 x 3 = 15

THEN..

25 - 15 = 10

Then the answer is 10

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)
