There are 6 red marbles and 7 blue marbles in a bag. (a) What is the ratio of all marbles in the bag to blue marbles?

(b) What is the ratio of red marbles to blue marbles?

A) 13:7 or 13 to 7

B) 6:7 or 6 to 7

Step-by-step explanation:

For the first one it is just the total number of marbles to the total blues marbles. For B it is the total red marbles to the total amount of blue marbles.

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)

it would be less than 25
