Answer:
The short piece is 3 feet long.
The long piece is 6 feet long.
Answer:
24 ft up the wall
Step-by-step explanation:
We can use the Pythagorean theorem to solve, letting the 25 ft ladder be the hypotenuse
a^2 +b^2 = c^2
7^2 +b^2 = 25^2
49 + b^2 = 625
Subtract 49 from each side
49-49 +b^2 = 625-49
b^2 = 576
Take the square root of each side
sqrt(b^2) = sqrt(576)
b = 24
We only take the positive solution since length cannot be negative
The ladder will reach 24 ft up the wall
900 centimeters is the answer to this question
First, we group together the terms with variables in one side by subtracting 3/2 x and 5 from both sides of the equation.
(2/3)x - (3/2)x + 5 - 5 = (3/2)x - (3/2)x - 5
(-5/6)x = -5
The value of x from the equation is 6.
