Firstly, the negative power sign flips the number the 1/125.The 1/3 part of the power means find the cubic (3rd) root. 1/5Finally the 2 of the power means square the number. 1/25 is therefore the final an...

To solve this we form two simultaneous equations. To make things easier lets denote apples as A and bananas as B. So this means we can write the above information in two equations like so: EQ1) 2A + 3B = ...

The unknowns of x and y are the same in each equation, allowing us to combine the two in order to find out their values.The substitution method can be used in most cases if the coefficient is the same wit...

First label your two simultaneous equations1)2x+y=42)3x+2y=6Then rearrange 1)1*) y=4-2xNow sub 1*) into 2)3x + 2(4-2x)=6and expand brackets and solve for x3x+8-4x=6-x=-2x=2Now sub x=2 into 1)2(2)+y=4y=0

To find the y value at A, we know that x is equal to zero. This can be put into the equation of the line so that 3(0)+2y=6. Therefore 2y=6, and to get the y value, we divide each side by 2, giving us y=3 ...
