<span>9.8 crops up in a number of situations. The force of gravitational attraction on a mass of 1 kg on the Earth is 9.8 N. ... Strictly speaking the force of gravitational attraction on a mass in a gravitational field of N/kg is although the in that equation is often called the acceleration due to gravity. Hope this helps!!!</span>
Answer:
y=21 X=39
Step-by-step explanation:
expand brackets on first equation: 2x+2y=120
now divide the second equation by 2 on both sides:
2x+y/3=85
then subtract the second equation from the first equation
so (2x+2y) - (2x+y/3)
the 2x on both sides cancel out and you get 5/3 y
this is equal to the sum of the first equation subtract the second equation which is 35
divide both sides by 5/3 and you get
y=21
substitute y in the first equation and you get X=39
Lets say for arguments sake that the bag contained 2 blue and 3 red marbles
p:q = 2:3 In order to get a ratio of 2:1 we would have to add 4 blue marbles
(6:3 = 2:1).
So the ratio p to r = 2:4 = 1:2 answer.
