First subtract 8 from both sides so 6x+8-8=50-8
Which is 6x=42 then divide both sides by 6:
6x/6=42/6
x=7

X = 7 . You have to subtract the total from the amount your adding, then divide the 6. then you get your answer

the area of 4 walls and ceiling of a room is 107 metre per square. if the room is 6m long and 5m wide, how high is the room?

lawyer [7]

Area of ceiling: 6 x 5 = 30 square meters:

Area of 4 walls = 107 - 30 = 77 square meters

2 walls = 6 + 6 = 12 meters long

2 walls = 5 + 5 = 10 meters long

12 + 10 = 22

77 square meters / 22 meters = 3.5 meters

The walls are 3.5 meters high.

A red die is tossed and then a green dieis tossed. What is the probability thatthe red die shows a six or the green dieshows a s

mr_godi [17]

Let's call the event of the red die to show a six as event A, and the event of the green die to show a six as event B.

The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes. On both dices, we have 6 possible outcomes(the numbers from 1 to 6), with one favourable outcome(the number 6), therefore, the probabilities of those events are:

$P(A)=P(B)=\frac{1}{6}$

Each roll is independent from each other, then, the probability of both events happening simultaneously is given by their product:

$P(A\:and\:B)=P(A)P(B)$

Using the additive rule of probability, we have the following equation for our problem:

$\begin{gathered} P(A\:or\:B)=P(A)+P(B)-P(A\:and\:B) \\ =P(A)+P(B)-P(A)P(B) \\ =\frac{1}{6}+\frac{1}{6}-\frac{1}{6^2} \\ =\frac{2}{6}-\frac{1}{36} \\ =\frac{12}{36}-\frac{1}{36} \\ =\frac{12-1}{36} \\ =\frac{11}{36} \end{gathered}$

the probability that the red die shows a six or the green die shows a six is 11/36.

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods trai

Flauer [41]

The length of the goods train is 270 meters.

Given that, a goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds.

<h3>What is the distance formula with speed and time?</h3>

Speed is defined as the rate at which an object moves from one place to another in a given interval of time. It is a scalar quantity as it defines only the magnitude not the directions of an object moving. The S.I. unit of speed is m/s.

The speed of a moving object can be calculated as Speed = Distance / Time.

Now, to convert km/h to m/sec multiply the measure by 5/18.

That is, 72 × 5/18 = 20 m/sec

Let the length of the train be x metres.

So, then (x+250) / 26 = 20

⇒x+250=520

⇒x=270 meters

Therefore, the length of the goods train is 270 meters.
