Write an expression to represent: The sum of ten and the quotient of a number x and 6.
Minchanka [31]
Let us break it down. A sum of ten. That is just 

+10

Then, we will add that to the quotient (which is the number after dividing) of a number x and 6. We can write that as 

+ x/6

The slash means division here. Thus your final answer is 


10 + x/6

Ugo [173]

Answer: 20\ cm

Step-by-step explanation:

The first step to solve the exercise is to make the conversion from meters to centimeters.

Since 1\ m=100\ cm, then the dimensions of the wood board in centimeters are:

Lenght=100\ cm\\\\Width=60\ cm

Now, you must find the Greatest Common Factor (GCF). The steps are:

- Descompose 100 and 60 into their prime factors:

100=2*2*5*5=2^2*5^2\\60=2*2*3*5=2^2*3*5

- Multiply the commons with the lowest exponents:

GCF=2^2*5\\\\GCF=4*5\\\\GCF=20

Therefore, the side lenght of each square must be:

s=20\ cm
