Richard, Angad and Paul share £108 in a ratio 2:3:1. How much money does each person get?

Step-by-step explanation:

If R, A, and P all share 108 pounds in the ratio of 2 to 3 to 1, then

2x + 3x + 1x = 108 and

6x = 108 so

x = 18.

R holds the ratio of 2x, so he gets 2(18) which is 36;

A holds the ratio of 3x, so he gets 3(18) which is 54;

P holds the ratio of 1x, so he gets 1(18) which is 18.

36 + 54 + 18 better equal 108...and it does!

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
