the question in English
Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?
Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that
Juan wants that the two columns to be the same height
so

solve for y

I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
<u>the answer is</u>
9 blue cubes
11 red cubes
Answer:
the answer is 196
Step-by-step explanation:
4x+4=60
4x+4-4=60-4
4x=56
56/4=14
14×14=196
Answer:
The correct answer to the following question will be "60 students".
Step-by-step explanation:
Marta will be taking a sampling frame from some kind of 600 student group.
Mean,
N = 60
Although the sampling method could perhaps consist of the following components 10% of the population,
⇒ 
⇒ 
In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.
