Maths Exam Algebra & Number Year 9

To find the value of WX divided by Y, we substitute the given values of w, x, and y into the expression. Since w is 9, x is 4, and y is -2, we have (9 * 4) / (-2). This simplifies to 36 / -2, which is equal to -18. Therefore, the correct answer is -18.

The given answer is obtained by combining the individual elements in the given sequence: d+d+d+d+d+d+a-i. By combining the six instances of "d" together, we get "6d". Then, by combining the "a" and "-i" together, we get "a-i". Therefore, the correct answer is "6da-i".

The given expression can be simplified by combining like terms. The terms 2k, 3k, 4k, and -2k can be added together, resulting in 7k. Therefore, the simplified form of the expression is 7k. 

The given expression involves combining like terms. We have 14k and 11k, which can be combined to give 25k. Similarly, we have -6y and -y, which can be combined to give -7y. Therefore, the simplified expression is 25k-7y. 

-6 times 3 is not equal to 18. The correct result is -18. When you multiply a negative number (-6) by a positive number (3), you get a negative result.

The given numbers are arranged in descending order based on their values. Starting from the highest value, the numbers are: 9.37, 9.356, 9.35, 9.305, 9.289, 9.27.
