Answer:
[tex]\boxed{11}[/tex]
Step-by-step explanation:
The ratios of corresponding segments are the same, so you can write ...
(3x +7)/5 = 48/6
Multiplying by 5 gives ...
3x + 7 = 40
3x = 33 . . . . . . subtract 7
x = 11 . . . . . . . . divide by 3
_____
Please note that the value (3x+7) is missing units. If this is 3x+7 cm, then the value of x is 11 cm. If this is (3x+7) cm, then the value of x is 11 (no units).
