Answer:
The correct answer is the equation stands as 4x =40 where x is the number of pages Naomi would require and the value of this x is 10.
Step-by-step explanation:
Number of countries that competed in 1900 summer Olympic games is 28.
Number of countries that competed in 1904 summer Olympic games is 12.
Total number of countries competed in total is 40.
Each page of Naomi's report contains information about 4 of the countries that competed each year.
Let Naomi need x number of pages to incorporate the whole report.
Thus the equation now stands as 4 × x = 40.
⇒ x = 10.
Thus Naomi would require 10 pages to complete her report.
Answer:
5x + 2y + z
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all the sides of the polygon. This polygons has 8 sides. Their lengths are:
x, x, x, x, x, y, y, z
The perimeter of the polygon is the sum of the lengths shown above.
perimeter = x + x + x + x + x + y + y + z
The expression above can be simplified by combining like terms.
perimeter = 5x + 2y + z
