. A rational number is such that when you multiply it by 5/2 and add ⅔ to the product, you get

(-7/12). What is the number?

(a) ½ (b) ⅓ c) (-½ ) (d) (-⅓)​

Answer 1

Answer:

(c) (-1/2)

Step-by-step explanation:

1) Combine multiplied terms into a single fraction

5/2x = (-7)/12 - 2/3

2) Multiply the numbers

5x/2 = (-7/12) - 2/3

3)Subtract the numbers

5x/2 = (-7) - 8 / 12

5x / 2 = (-15)/12

5x/2 = (-5)/4

5x = (-5)/4 x 2

5x = (-5)/2

x = (-5/2) x 1/5

x = (-1/2)
