First we get rid of the first mixed fraction by making it top heavy:1=5/5, therefore 1 1/5= 6/5Then we flip the second fraction to get its reciprocal: 4/3Now we change the sign to multipl...

We can take 1 away from all elements to obtain 4 < x² < 9. Now, it's important to notice that when we square a negative, it gives us a positive, so when we take a square root to get 2 < x < 3 ...

First thing to observe here, is that this equation is somewhat different to what you would find normally. This is a complex equation. How can you tell? The third term, ie 32i(sqrt(3)) contains the symbol ...

We want to find the values of x for which this inequality is 0. Let's first fine the values of x for which x²- 7x = -6.Rearranging, x² - 7x + 6 = 0. Now we're looking for the values ...

Number of lemons = m - 3. Construct a tree diagram using the information given to represent picking two fruits out of the basket (without replacement) one after the other. Since picking each fruit is an i...
