What's the value for x makes this equation true 3/5 X-0.5=19

what's the value for x makes this equation true 3/5 X-0.5=19  HERE YOU GO!!

Step-by-step explanation:

-5x - (-7 - 4x) = -2(3x - 4)

-5x + 7+ 4x = -6x + 8

-x + 7= -6x + 8

5x = 8 - 7

5x = 1

x = 1/5

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
