Help plz I have 6 minutes

x = 105

Step-by-step explanation:

Sum of n-sided polygon = (n - 2)*180

The polygon given is a 7-sided polygon, therefore substitute n = 7 into (n - 2)*180

Sum of the polygon = (7 - 2)*180 = 900°

Thus:

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900

Add like terms

2x + 690 = 900

2x = 900 - 690

2x = 210

x = 210/2

x = 105

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
