Let's call the numbers we are looking for a and b. From the question: a-b = 50 and b is 50% of a, which means that b = (50/100)a=0.5 a. Substituting this form of b in the first equation, we obtain: a-...
First we can equate (19x - 2)/((5 - x)(1 + 6x)) to A/(5-x) + B/(1+6x) which means: (19x - 2)/((5 - x)(1 + 6x)) = A/(5-x) + B/(1+6x). Then we will turn the RHS into a single fraction: (19x - 2)/((5 - x)(1 ...
While this problem could be done simply by inputting the appropriate numbers into the correct formula, it is good practice to draw a diagram of the problem in order to minimise any silly mistakes that may...
The question asks you to calculate 27-3/2.Due to the presence of the negative sign, 27-3/2 is the same as 1/273/2. The fractional power is a little more tricky...
In order to answer this question, we will follow the FOIL procedure. First, Outter, Inner, Last. Using the 'F' we will multiply the first 2 numbers of each bracket. In most cases, these 2 variables will h...
