Answer:
x=22
Step-by-step explanation:
Since the two triangles are similar we can set up two ratios...
(sorry if these numbers are wrong the picture isn't very clear)
38:15.2
We can simplify this ratio into...
2.5:1
Now we solve for x
55:x
We divide 55 by 2.5
55/2.5=22
x=22
Answer: 3x - 9
Step-by-step explanation: "9 less than three times a number" does not mean 9 minus three times a number, less than actually switches the order around so that 9 less than three times a number actually means three times a number minus 1 which can be read as 3x - 9.
The concept that is useful in order to answer this item is the concept of ratio and proportion. Let x be the height of the rock from the ground. We use the equation below to answer.
5.5 ft / 18 ft = x ft / 209.5 ft
The value of x from the equation is 64 ft. Thus, they will be needing approximately 64 ft of rope.
