Answer:

  Use the Pythagorean theorem: (5/8)^2 +(3/2)^2 = (13/8)^2 ⇒ right triangle

Step-by-step explanation:

Check to see if the numbers satisfy the Pythagorean theorem.

  (5/8)^2 + (3/2)^2 = (13/8)^2

  25/64 + 9/4 = 169/64

  25/65 +144/64 = 169/64 . . . . . . . true. The triangle is a right triangle.

__

If a, b, c represent the lengths of the sides, least to greatest, then ...

  a^2 + b^2 > c^2 . . . . acute triangle

  a^2 + b^2 = c^2 . . . . right triangle

  a^2 + b^2 < c^2 . . . . obtuse triangle

<em>Additional comment</em>

A triple of integers that satisfy the Pythagorean theorem (form a right triangle) is called a "Pythagorean triple." One you see often, and that has the special property that it is <em>the only triple that is an arithmetic sequence</em> is (3, 4, 5). A couple of other common ones are (5, 12, 13) and (7, 24, 25).

Any of these can be scaled by a common factor to make sides of a right triangle. Here, we have (5, 12, 13) scaled by a factor of 1/8 to make (5/8, 12/8, 13/8) = (5/8, 3/2, 13/8) — the numbers in the problem statement.

If you're aware of these common triples, you can check to see if they are being used in any right-triangle problem you may run across. Recognizing that one of these applies can save you the effort of working out the squares and/or root that would otherwise be involved.

How many solutions does the equation −3x−17=−17−3x have?
harkovskaia [24]

Answer:

an infinite number of solutions

Step-by-step explanation:

−3x −17 = −17 −3x

left side = right side  TRUE because -3x-17 is the same as -17-3x

we can rearrange  the the equation

−3x −17 +17 = −17 +17−3x, add 17 on both sides of the equations

            -3x = -3x, divide both sides by (-3)

               x = x

Since this equation is <u>always true ( for any number ) </u>we have <u>an infinite number of solutions</u> (since there are is an infinity of numbers.)

Why would I rewrite this
Ratling [72]

You are finding 3 1/6 - 1 5/6.

To solve, you should first change it so that the numerator of the first fraction is greater than the numerator of the second. Note that both have the same denominator (6). Subtract as usual:

3 1/6 = 2 7/6

2 7/6 - 1 5/6 = 1 2/6

1 2/6 is your answer.
