Number of pencils x
number of pens y
3x + y = 10
x ≤ y
Draw the line 3x + y = 10 .[it passes by (0,10) and (-10/3,0)
Draw the line y=x [it passes by (0,0), (1,1), (2,2) etc]
Then the solution is the points with integer x and y, that belong to the segment of the line 3x +y = 10 between the x-axis and the line y=x. Those points are (1,7) , (2,4), (3, 1).
Good Question!
So since we know that a square is exactly the same all the way around we can assume that both diagonals in the square are the same. This means that they form a right triangle in the middle with two legs of 3.75!
So to find the side of the triangle we use a^2 + b^2 = c^2
3.75^2 + 3.75^2 = c^2
28.125 = c^2
<span>√(28.125) = c
</span>c = 5.3
Now finally we just square 5.3 again to find the area of the square and it's 28.1mm^2!
So the answer is the third one! hope this helps!
