If the sum of two numbers is 12 and also the an initial number is x,the various other numbers is 12 - x. This time the expression is the an outcome of resolving an equation. Intend the amount of two numbers is 12. Algebraically this is written as x + y = 12. resolve for y: x + y = 12 -x -x--------------- y = 12 - x If the amount of two numbers is 12 and also the first number is x,the various other numbers is 12 - x. You can even examine this answer. x + y = 12 x + (12 - x) = 12 x + 12 - x = 12 12 = 12 5.

The sum of 2 numbers is 12.So, one number is x and also the other is 12 - x. If the smaller sized number is double and included to the bigger number, the an outcome is 16.2(smaller) + (larger) = 162(x) + (12 - x) = 162x + 12 - x = 16x + 12 = 16x = 8 and also 12 - x = 4The numbers room 8 and 4.5b. An edge is three times the size of that complement. Uncover the angles. So, one edge is x and the other is 90 - x. An edge is 3 times the size of that is complement. (angle) = 3(complement)(x) = 3(90 - x)x = 270 - 3x4x = 2704x/4 = 270/4x = 67.7 for this reason 90 - x = 22.5The angles measure 22.5° and 67.5°. 5c. There room 12 coins in a bank and also the coins have a value of $1.20.
