Answer:

1/2 = x

Step-by-step explanation:

8 (x-3) + 7 = 2x (4 - 17)

8 (x-3) + 7 = 2x (-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

-17 = -34x

1/2 = x

irga5000 [103]

It seems that you are trying to find the length of hair of Florencia on Tuesday.

On Tuesday, she got hair cut.

So new length of the hair of Florencia on Tuesday = 75% of Monday value

= 75% of (h)

= 0.75* (h)

= 0.75h

Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.
