7(x + 1) = 63
That is the equations of the words above. The simplified version is:

7(x + 1) = 63
7x + 7 = 63 (multiplied 7 by x and the 7 by 1)
- 7 -7
-----------------
7x = 63
---- ---- (divide by seven to leave the variable, in this case the letter x, alone)
7 7
x = 9 (63/7 = 9)

A car travels a total distance of 150km. At the 50 minutes mark the car has travelled 50km and at the 110 minutes the car has tr

Answer:

The average velocity is 19.44 m/s.

Step-by-step explanation:

The average velocity between two points can be calculated with the following formula:

$\bar v=\dfrac{\Delta X}{\Delta t}=\dfrac{(120-50)\, km}{(110-50)\, min}=\dfrac{70\,km}{60\,min}\\\\\\\bar v=1.667\dfrac{km}{min}*\dfrac{1\,min}{60\,s}*\dfrac{1000\,m}{1\,km}=19.44\dfrac{m}{s}$

The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.

Focus on number two ok

melomori [17]

Its simple, convert 1 and 2/3 into a fraction which is 5/3 and use KCF which is Keep Change and Flip,

How this works is that you keep the first fraction, then change the division sign to a multiplication sign (Change = change the sign into its oppisite) then flip the other fraction from being 5/3 into 3/5. And then you multiply top times top and bottom times bottom. After that you simplify if you can, Hope this helped!

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

$=\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349$
