Answer:
y = 2
Step-by-step explanation:
Given
= 
( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Add 2 + 1 = 3 then 1/2 +1/2 =1
so 3 +1 = 4 and you have 1/4 left so your answer is 4 1/4
The length of the support cable is about 29 feet.
If you sketch out the question, you will see that it will form a right triangle with the cable as the hypotenuse.
Just set up and use the Pythagorean Theorem.
15^2 + 25^2 = c^2
850 = c^2
29.15 = c
