X= # of eraser packages = 135 
y= # of pencil packages = 85 

cost = 2x + 5y = 695
# of items = x+y= 220
                                                             2x+5y=695 
                                                            -2x -2y=-440
                                                              3y             255
                                                             -----     =     -------       y=85             x+(85) / 220
                                                                3                3                                       -----    -----
                                                                                                                            -85     -85
                                                                        
                                                                                                                               x=135 
2(135) + 5 (85) ?695
270+425?695

patriot [66]
We are given two sides of a triangle that are 2 and 5 and the angle between them is pi/3 or 60 degrees. In this case, we can use the cosine law to relate the given dimensions and angle. The cosine rule goes c2 = a2 + b2 - 2abcos C; Substituting, c2 = 4 + 25 - 2*2*5*cos pi/3 ; c2 = 19; c = sqrt 19 = 4.36 units.

What is the area of the figure? <br> A. 54 cm2<br> B. 42 cm2<br> C. 54 cm<br> D. 42 cm
serg [7]

Answer

The area is 54cm² To get the area i split the shape into two shape both having a length of 9in and a width of 3in. I calculate the area for one by using lxw=area and get 27 and times that by two to get 54.

When calculating the area for this object you get 54 and you add the ²symbol because its area is not one dimensioned it is two dimensioned or length times width not just length, so you use the ² symbol to show that.
