Answer

Given,

Mass of bag = 6 Kg

Area covered by the bag = 2.5 x 5 = 12.5 m²

a) Bags required to cover area = 7.5 x 10.2

                                                    = 76.5 m²

 Number of bags, N = \dfrac{76.5}{12.5}

                               N = 6.12 = 7 (approx.)

7 Bags of 6 Kg fertilizers will be needed to cover the area.

b) Cost of 6 Kg fertilizers = $15.50

  Cost of 7 bags of 6 Kg fertilizers = 7 x $15.50

                                                         = $108.50.

mezya [45]

Answer:

<h2>9x - 13</h2>

Solution,

f(X)= 2x-1

g(X)= 7x-12

Now,

h(x) = f(x) + g(x) \\  \:  \:  \:  \:  \:  = 2x - 1 + 7x - 12 \\  \:  \:  \:  \:  = 2x + 7x - 1 - 12 \\  \:  \:  \:  \:  \:  = 9x - 13

Hope this helps...

Good luck on your assignment...
