What is the value of x?

Step-by-step explanation:

If you were really careful, you should say there is no solution. You have to know that x and 8 are parallel.

The side showing 6 and 6 are sides of a large and small triangle

The large triangle is 6 + 6 = 12

The small triangle is 6

So 8 and x are going to be in the same proportion.

x/6 = 8/12      Cross multiply

12x =48

x = 48/12

x = 4

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

his chances of getting a coin of higher value is 4/19
