Before you continue with the page, express to yourself exactly how you came down on each various other number as soon as the sum of 2 numbers is 12.If you supplied subtraction, component 3 will describe your method. If you supplied addition, component 4 will define your method.3. If the sum of two numbers is 12 and also the very first number is x,the various other numbers is 12 - x. 1st number2nd numbersumBecause:1111212 - 12101212 - 2661212 - 6481212 - 4 x12 - x1212 - x 4. If the amount of 2 numbers is 12 and the first number is x,the other numbers is 12 - x. This time the expression is the an outcome of resolving an equation. Mean the sum of 2 numbers is 12. Algebraically this is composed as x + y = 12. settle for y: x + y = 12 -x -x--------------- y = 12 - x If the amount of two numbers is 12 and also the very first number is x,the various other numbers is 12 - x. You deserve to even inspect this answer. x + y = 12 x + (12 - x) = 12 x + 12 - x = 12 12 = 12 5. Uses of this this an approach review the meanings of: complement, safety angles, supplement, supplementany angle Review how to compose code as a step in solving word problems. settle the problems below and check the price after every problem. 5a. The amount of 2 numbers is 12. If the smaller sized number is double and included to the bigger number, the an outcome is 16. Find the numbers. 5b.

© 01-6-3www.chathamtownfc.net/math/algebra/qb/otherno.htm5a. The sum of two numbers is 12. If the smaller number is doubled and added to the larger number, the result is 16. Uncover the numbers. 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 added to the larger 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 are 8 and also 4.5b. An edge is three times the dimension of that complement. Find the angles. So, one angle is x and also the other is 90 - x. An edge is 3 times the dimension of that is complement. (angle) = 3(complement)(x) = 3(90 - x)x = 270 - 3x4x = 2704x/4 = 270/4x = 67.7 therefore 90 - x = 22.5The angles measure 22.5° and also 67.5°. 5c. There room 12 coins in a bank and the coins have actually a worth of $1.20.

The room five more dimes than nickels and also all the rest of the coins room quarters. Uncover how many dimes are in the bank.(nickels) + (dimes) + (quarters) = 12(total value) = $1.20 .05(nickels) + .10(dimes) + .25(quarters) = $1.205(nickels) + 10(five an ext than nickels) + 25(quarters) = 1205(x) + 10(5 + x) + 25(quarters) = 1205(x) + 10(5 + x) + 25(the rest of the 12 coins) = 1205(x) + 10(5 + x) + 25(12 - (x + 5 + x)) = 1205(x) + 10(5 + x) + 25(12 - 2x - 5) = 1205x + 50 + 10x + 25(12 - 2x - 5) = 12015x + 50 + 25(7 - 2x) = 12015x + 50 + 175 - 50x = 120-35x + 225 = 120-35x = -105x=3x=3, and x + 5 = 8, and also 12 -(x + 5 + x) = 1The space 3 nickels, 8 dimes, and one quarter.
