x=

Answer 1

x = 12.5 but that is not an option...

so I don't know...

Explanation:

5: 4 = x : 10

Write this as fractions and after cross multiplication you get:

5*10 =4*x

x=10*(5/4)

x = 12.5

Answer 2

Multiply the dimensions of 1 line together to equal the other line:

10 x 4 = 5x

40 = 5x

X = 40/5

X = 8
