This would be a question that would test the students understanding of Pythagoras' Theorem. When teaching this before I have often found that students are scared of thee questions because of the name, so I w...

To find what x is, we must rearrange the equation so that it says x=. To do this we need to get rid of the -3 on the left hand side of the equation. This can be done by adding 3 to both sides of the equation...

Elimination: Multiply equation (eqn) 1 by 2 : 2y=2x-10 Subtract modified eqn 1 from 2 : 8y=16 Divide through by 8 : y=2 Sub y=2 into eqn 1 or 2 and rearrange to find : x=7 Subsitution: Sub eqn 1 into eqn 2 :...

this means that there are 5 parts to share out altogether. (2+3=5) So you take the value you wish to share and divide it by 5. once you've divided the value by five, to share in the ratio 2:3 simply means to...
