Enter the number that belong n the green box.
Please help me , I would really appreciate it!

Step-by-step explanation:

(2x + y) + (3x - y) = 180°   {straight line}

2x + y +3x - y = 180

2x + 3x + y -y =180

5x +0 = 180

5x = 180

x = 180/5

x = 36

5y  = 3x - y       {Vertically opposite angles are equal}

5y = 3*36 - y

5y = 108 - y

5y + y =108

6y = 108

y =108/6

y = 18

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
