Answer 2

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. x/2 - 5 = 10;

x/2 = 10 + 5 (using the addition property of equality)

X/2 = 15

X = 15×2 ( using cross multiplication)

X = 30

2. Interior angles of a polygon

Hexagon has 6 sides this would be the value of n.

To get the interior angles we use the formula (n-2)(180)/n

Substitute n: (6-2)(180)/6

Solve: (4)(180)/6 = 720/6 = 120.

Hexagon's interior angle measures 120° .

3. 1. Because the square of 9 is 81.

4. -9(3) = -27

5. Reciprocal of -2 1/7 is -7/15

6. 13
