140, 280, 420, 560, 700
there are 6: 21,28,35,42,49,56
-27
They are: 20, 40, 60, 80, 100 and 120
Multiplies by 3, then subtracts 7
5 10 15 20 25 30
3 and 7 multiplies to 21 and equals to 10
7, 31
the first 5 multiplies of 5 are 5, 10, 15, 20, 25
To find two numbers that add to 20 and multiply to 29, we can set up a system of equations. Let's call the two numbers x and y. We have the following equations: x + y = 20 and x * y = 29. By solving these equations simultaneously, we find that the two numbers are 5 and 15.
