Step 1: Write down the information we got in a simplified form => cement (c) .... 7 bags .... 5 bags, gravel (g) ...... 3 bags .... 4 bags, total weight .. 215kgs ... ...

2(x-2) = 3x+9LHS = RHS2x-4 = 3x+92x-3x = 9+4-x = 13x = -13

This is a question that requires multiple steps, and in the exam may be worth around 3 marks. One will be for expanding, one for simplifying, and one mark for working.First step: expand the brackets. This...

1.) y²/x2.) x²+2y3.) xy4.) y²-2x²

8x + 32
Highest common factor of 8 and 32 is 8
8/8 = 132/8 = 4
8x + 32 - divide through by 8
8(x + 4)
We can check this by multiplying out:
8(x + 4) 8 * x = 8x 8 * 4 = ...
