4) a safe contains 120 coins, the value of which is $10. if the coins consist of nickels and dimes, how many of each kind are in it? 5) a sum of $14 is made of 92 coins, consisting of dimes and quarters. how many are there of each kind of coin? 6) a boy's coins, consisting of nickels and dimes, amount to 42.15. if the number of dimes exceeds 3 times the number of nickels by 4, find the number of each kind of coin?

step-by-step explanation:

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)
