Solve the simultaneous equations. 3x + 5y = 1 , 2x - 3y = 7

3x + 5y = 1 (eq 1) 2x - 3y = 7 (eq 2) Step 1 - 2* (eq 1) 6x + 10y = 2 (eq 3) Step 2 - 3* (eq 2) 6x - 9y = 21 (eq 4) Step 3 - eq 4 - eq 3 to cancel the x -19y = 19 Therefore, y = -1 (eq 5) Step 4 - sub (eq 5)...

A circular table top has diameter 140 cm. Calculate the area of the table top in cm² , giving your answer as a multiple of π.

So we know the formula for the area of a circle: πr 2 So all we need to find is the radius 2 Radius = Diameter / 2 (Half the diameter) = 70 Radius 2 = 70 2 = 4900 Therefore using our original equation: πr 2 ...
