What is the length of pr ? PLEASE HELP

Karolina [17]

The angles in the triangles are the same, so you know the triangles are similar. Sides PQ and AB correspond as do sides PR and AC. Because the triangles are similar, you know that
PR/AC = PQ/AB
PR/24 = 5/20
Multiplying this equation by 24 gives
PR = 24*(5/20) = 6

The appropriate choice is ...

Answer:

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}$

Step-by-step explanation:

Given

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n);m=\frac{1}{2},n=\frac{1}{3}$

Required

Solve

To do this, we simply substitute values of m and n in the given expression

$\frac{3}{4}(\frac{1}{2}+\frac{1}{3})-\frac{1}{4}(\frac{1}{2}-\frac{1}{3})$

Evaluate the brackets

$\frac{3}{4}(\frac{3 + 2}{6})-\frac{1}{4}(\frac{3-2}{6})$

$\frac{3}{4}(\frac{5}{6})-\frac{1}{4}(\frac{1}{6})$

Open Brackets

$\frac{15}{24} - \frac{1}{24}$

Take LCM

$\frac{15 - 1}{24}$

$\frac{14}{24}$

Hence:

$\frac{3}{4}(m+n)-\frac{1}{4}(m-n) = \frac{14}{24}$
