What is the average of 31.8, 43.8, 29.2, 31.0, and 53.8?

37.92

Step-by-step explanation:

To find the average of something add all of the numbers and then divide by how many numbers there are

31.8 + 43.8 + 29.2 + 31 + 53.8 = 189.6

189.6 ÷ 5 = 37.92

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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
