Each box contains 24 pens...and u need 266 pens..
266/24 = 11.08....u would need to buy 12 boxes.....because 11 boxes would only have (11 * 24) = 264 pens
answer : 12 boxes
Hello,
The slope of the 1st side is 2 (y=2x)
The slope of the 2 nd side is -1/2 (y=-x/2+5/2)
The two sides are perpendicular so we can find the vertex.
y=2x (1)
2y+x=5
If we substitue y by is value in (1)
2(2x)+x=5==>5x=5
==>x=1 and y=2*1=2
Vertex is (1,2)
In order to find the rectangle we must know an other vertex.
19/30 is already in simplest formed
