Point J is on line segment IK. Given JK = 2x, IJ = 5x, and IK = x + 6, determine the numerical length of JK.
Andre45 [30]

Answer:

JK = 2

Step-by-step explanation:

Given:

JK = 2x

IJ = 5x

IK = x + 6

Required

Solve for JK.

Since J is on IK, we have:

IK = IJ + JK

x + 6 = 5x + 2x

x + 6 = 7x

Collect Like Terms

7x - x = 6

6x = 6

Solve for x

x = 6/6

x = 1

Substitute 1 for x in JK = 2x

JK = 2 * 1

JK = 2

The formula for the area of a triangle is A=bh/2. The area of a triangle is 26 cm squared and its base is 12cm. Using algrebra,
Fed [463]

Answer:

<em>4 and 1 / 3 cm</em>

Step-by-step explanation:

Consider the following;

A = 1 / 2 * Base * Height,\\26 cm^2 = 1 / 2 * ( 12 cm ) * Height

Let us say that Height = x. If that is so, through algebra, let us solve for x;

26 cm^2 = 1 / 2 * ( 12 cm ) * x,\\26 cm^2 = 6 cm * x,\\26 cm^2 / 6 cm = x,\\\\x = 26 cm^2 / 6 cm,\\x = 4 and 1 / 3\\\\Conclusion, Height = 4 and 1 / 3 ( cm )

<em>Solution ⇒ 4 and 1 / 3 cm</em>
