Question

Two redwood trees are the same height. A third tree's height is x feet. The first tree is 50 feet more than three times the height of the third tree. The second tree is 100 feet taller than twice the height of the third tree. What is the height, in feet, of the third tree? A. 150 B. 50 C. 200 D. 100

Answer 1

3rd tree = x

1st tree = 3x+50

2nd tree = 2x+100

3x+50 = 2x+100

subtract 50 from each side

3x= 2x+50

subtract 2x from each side

x = 50

 so 3rd tree = 50 feet tall

 Answer is B
