Learning Task 2: Solve each proportion 1) 5/12 = 35/ n

2) n/ 52 = 180/ 120

3) 18/n = 21/28

4) n/4 = 24/6

5) 10/16 = n/56

Bonjour,

1) 5/12 = 35/ n

(5/12) /35 = n

5/12 * 1/35 = n

5/420 =n

1/84 =n

2) n/ 52 = 180/ 120

n= (180*52)/120

n=9 360/120 = 936/12 = 78

3) 18/n = 21/28

n = (21/28)/18

n = 21/28 * 1/18

n= 21/504 = 7/168= 1/24

4) n/4 = 24/6

n= 24/6 * 4

n= 96/6 =16

5) 10/16 = n/56

n= 10/16 * 56

n= 560/16

n= 35

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
