A sum of money is divided in ratio 3:5:9 . Calculate the smallest share given that the largest share is $558

1 answer:

3 0

First work out the 'multiplier'

3 + 5 + 9 = 17 so Multiplier = 1/17

$558 is the largest share and that equals 9 * 1/17 of x where x is the total amount of money

9x / 17 = 558

x = (558 * 17) / 9 = $1054

So the smallest share = 3 /17 * 1054 = $186 Answer

Answer:

y = 10x + 15

Step-by-step explanation:

you pick two points on the line

I picked (3,45) and (6,75)

you subtract the two x’s and y’s

75 - 45 = 30 (30 is the rise) you go up from 45 to 75

6 - 3 = 3 (you move 3 times to the right to get to the 6) so 3 is the run

slope = rise/run so 30/3 = 10
