Explanation

Green ratio = 5 parts = 60

1 part = 60 ÷ 5 = 12

Total ratio = 3 + 4 + 5 = 12 parts

Total value = 12 × 12 = 144

Explanation

Let the numbers be x and y, with x > y  

x + y = 52  

x - y = 8  

Add both equations:  

2x = 60 → x = 30  

Then y = 52 - 30 = 22  

Check: 30 + 22 = 52, 30 - 22 = 8

Explanation

x² - 9x + 20 = 0  

Factor: (x - 4)(x - 5) = 0  

So x = 4 or x = 5

Larger value = 5

Explanation

Let the number be x.

Twice the number = 2x

Packets are 4 more than twice:

2x + 4 = 38

Solve:

2x = 38 − 4

2x = 34

x = 17
