The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.
According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.
We can solve this problem by using the distance formula. The distance formula is: 
We can now put in values and solve.
One way is you can divide 30 by a certain amount
Answer:
x = 2
Step-by-step explanation:
Step 1: Convert to math
5x + 1 = 3x + 5
Step 2: Solve for <em>x</em>
- Subtract 4x on both sides: 2x + 1 = 5
- Subtract 1 on both sides: 2x = 4
- Divide both sides by 2: x = 2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(2) + 1 = 3(2) + 5
10 + 1 = 6 + 5
11 = 11
