Find the circumference of the circle. Round your answer to the nearest centimeter.
A. 8cm
B. 16cm
C. 79cm
D. 157

b. 16

Step-by-step explanation:

Since you have the radius, you have to multiply that by two to get the diameter.

The formula for the circumference is d(pi) so you multiply the diameter times pi.

Then you round that answer, 15.7, to the nearest centimeter, which is 16

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
