5 x(3+2) =5x(5)= 25

Rearrange one of the equations to make y the subject:y = 5 - 2x Substitute y into the other equation: 3x + 5 - 2x = 7 x = 2 y = 5 - (2 x 2) y = 1

When integrating, we raise the power by 1 and divide by the new powerSo, 2x⁵ becomes 2x⁶ /6 which simplified down as the question asks is x^6/3-1/(4x³) is -(1/4)x^^-3<...

12 items of fruit. 4/12 are apples - can 4/12 be simplified? Yes both can be divided by 4 and so the fraction becomes = 1/3 for the probability of taking an apple.
The probability of NOT taking an ap...

To make the equation easier, multiply it all by 2 : 6x-11 = 1 And solve: 6x = 12x = 2
