Find the value of x in the triangle. SU RV
kodGreya [7K]

Answer:

x = 8

Step-by-step explanation:

Δ TSU and Δ TRV are similar , thus the ratios of corresponding sides are equal, that is

\frac{TS}{TR} = \frac{TU}{TV} , substitute values

\frac{x}{x+16} = \frac{5}{15} = \frac{1}{3} ( cross- multiply )

3x = x + 16 ( subtract x from both sides )

2x = 16 ( divide both sides by 2 )

x = 8

on a recent hike through riverbend park antoinette traveled 2/3 mile in 1/3 hour . Which unit rate describes antoinettes speed i
My name is Ann [436]

Answer:

Her speed is of 2 miles per hour.

Step-by-step explanation:

Velocity:

The velocity is given by the following formula:

v = \frac{d}{t}

In which v is the velocity, d is the distance and t is the time.

2/3 mile in 1/3 hour .

This means that d = \frac{2}{3}, t = \frac{1}{3}

Which unit rate describes antoinettes speed in miles per hour?

This is v. So

v = \frac{d}{t} = \frac{\frac{2}{3}}{\frac{1}{3}} = \frac{2}{3}*\frac{3}{1} = 2

Her speed is of 2 miles per hour.
