Answer:

x = 21

Step-by-step explanation:

Given that SV is the angle bisector of ∠RST, then

∠RSV = ∠TSV, thus

∠RSV + ∠TSV = ∠RST ← substitute values

2x + 8 + 2x + 8 = 6x - 26, that is

4x + 16 = 6x - 26 ( subtract 6x from both sides )

- 2x + 16 = - 26 ( subtract 16 from both sides )

- 2x = - 42 ( divide both sides by - 2 )

x = 21

Alan solved the proportion StartFraction x over 200 EndFraction = StartFraction 8 over 25 EndFraction as shown. StartFraction x

bulgar [2K]

Answer:

Step-by-step explanation:

The proportion that Alan solved was

x/200 = 8/25

His working as shown was

(8)(x) = (25) (200)

8x = 5000

He divided both sides of the equation by 8. It became

8x/8 = 5000/8

x = 625

The correct steps are

25x = 200 × 8 = 1600

Dividing both sides of the equation by 25, it becomes

x = 1600/25

x = 64

Alan's error were:

1) He got the wrong product when he multiplied 25 by 200.

2)He got the wrong quotient when he divided 5,000 by 8.

An 5kg object is 6 meters what is the potential energy

AVprozaik [17]

Potential Energy of an object of 5kg which is 6 meters in height is 294 Joules.

Step-by-step explanation:

We are given:

Mass = m = 5 kg

Height = h= 6 meters

Potential Energy = ?

The formula used to find Potential Energy is:

$Potential\,\,Energy =mgh$

where m is mass, g is gravitational field and h is height

Putting the given values of mass and height, and g=9.8 m/s^2

$Potential Energy = 5*9.8*6\\Potential Energy = 294 Joules$

So, Potential Energy of an object of 5kg which is 6 meters in height is 294 Joules.
