What is 8x9 equals?
72
The sum of two numbers is 89. Four times the first number plus the second number gives 155. What are the two numbers?
Let the first number equal x and the second number equal y. You have: A) x + y = 89. B) 4x + y = 155. First you rearrange equation A to obtain equation C) y = 89 - x Then substitute C) into B) to obtain equation D) 4x + 89 - x = 155 Solve equation D) for x to obtain x = 22. Place the value of x in equation C) to obtain y = 67. Thus your answer is {x = 22, y = 67}.

Next number in series 298 209 129 58 -4?
298 less 209 is 89 209 less 129 is 80 129 less 58 is 71 58 less -4 is 62 The result of each subsequent equation is 9 less than the previous one (89, 80, 71...). The next result is going to be 62-9=53. The first number in each equation above is the same as the second number in the previous equation: 298 less 209 is 89 209 less 129 is 80So, the next equation will be: -4 less X is 53 Therefore, X is the next number in the original sequence, which resolves to: -57
