Answer:84
Step-by-step explanation:Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.
For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?
The rule of three is:
5.25 feet - 8 feet

Answer:
x+2y=2
-1x+1y=5
Step-by-step explanation:
Any system whose equations have the following characteristic
x+2y=2
-1x+1y=1
Is equivalent to the original system, since the differ in a number, the first equation is divided by 2 and the second by 5, we can say any system is equivalent to the original when it is escalated by a factor between its functions.
