If tb=5x and tu=4x-1 and ub=2x-1 what does x equal

1 answer:

3 0

If C is a point between AB then we can write AC + CB = AB

Same way we can write tu + ub = tb
tu = 4x - 1 , ub = 2x - 1 and tb = 5x
So we can write it as

$4x - 1+ 2x - 1 = 5x$

$6x - 2 = 5x$

$6x - 5x = 2$

$x = 2$

So x is = 2.

<h3>✽ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ✽</h3>

➷ Work out the time for Cardiff to Swansea:

time = distance/speed

Substitute in the values:

time = 69/60

Solve:

time = 1.15 hours = 69 minutes

Add together the total time and distance:

72 + 69 = 141

48 + 69 = 117

speed = distance/time

speed = 141/1.95

speed = 72.3 km/h

The planet Mercury travels in an elliptical orbit with eccentricity 0.203. Its minimum distance from the Sun is 4.5 x 10^7 km. I

Harrizon [31]

Answer:

Option C

Step-by-step explanation:

From the question we are told that:

Eccentricity $e=0.203$

Minimum distance from the Sun $d_s= 4.5 x 10^7 km$

Perihelion distance from a planet to the Sun is $r= a(1 - e)$

Aphelion distance $r'=a(1 + e)$

Generally the equation for Perihelion distance is mathematically given by

$4.5 * 10^7= a(1 - 0.203)$

$4.5 * 10^7 = 0.797a$

$a = 56.46 * 10^6 km$

Generally the equation for Aperihelion distance is mathematically given by

$r' = a(1 + e)$

$r' = 56.4617 * 10^6 (1 + 0.203)$

$r'=6.8 * 10^7 km$

Option C
