If TU=6, UV=4x, and TV=7x , what is TV?

balandron [24]

Answer:

Step-by-step explanation:

To find TV you must add the length of TU (6) by the length of UV (4x) to find x to find the length of TV(7x).

6+4x=7x

Do inverse operations to solve for x.

6=3x

x=2

Now that we know x is 2, we must substitute 2 in for the x in the equation for TV (7x).

7 × 2 = 14

TU = 14

El recorrido de una etapa de una vuelta ciclística tiene una longitud de 213 kilometros y un ciclista recorre 2/3 del trayecto e

Maurinko [17]

the question in English

The route of a stage of a cycle tour is 213 km long and a cyclist covers 2/3 of the route in five hours.

a) How many kilometers are left to finish the stage?

b) If he continues with the same average speed, how much time does he have left to finish the stage?

Step 1

we know that

1) Total kilometers of a stage is $213\ km$

2) The cyclist covers $\frac{2}{3}$ of the route

the kilometers remaining to finish the stage is equal to

$(1-\frac{2}{3})*213= \frac{1}{3}*213\\ \\=71\ km$

therefore

the answer Part a) is

$71\ km$

Step 2

Find the average speed of the cyclist

we know that

the speed is equal to

$speed=\frac{distance}{time}$

we have

$time=5\ hours\\ distance=\frac{2}{3}*213=142\ km$

substitute

$speed=\frac{142}{5}=28.4\frac{km}{h}$

Step 3

Find the time remaining to finish the stage

we know that

$speed=\frac{distance}{time}$

Solve for the time

$time=\frac{distance}{speed}$

we have

$distance=71\ km\\ speed=28.4\frac{km}{h}$

substitute

$time=\frac{71}{28.4}=2.5\ hours$

therefore

the answer Part b) is

$2.5\ hours$
