What is 2 1/8 take away 1/2​
goblinko [34]

The equation is 2\frac{1}{8} - \frac{1}{2} .

1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)

The new equation is \frac{17}{8} -\frac{4}{8} . Subtract the numerators.

17 - 4 = 13 or 13/8

The improper fraction \frac{13}{8} simplifies to 1\frac{5}{8} .

<h2>Answer:</h2>

1\frac{5}{8}

Hope this helps :)

Answer:

x ≈ 7.2

Step-by-step explanation:

Given a tangent- secant from an external point to the circle, then

the the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 4(4 + 9) = 4 × 13 = 52 ( take the square root of both sides )

x = \sqrt{52} ≈ 7.2 ( to the nearest tenth )
