Which of the following is not a valid conversion factor?
1 meter/100 centimeters. 1 ml/1 cm
1 kilometer/1000 meters
1 meter/10 millimeters

1 meter/10 millimeters is not a valid conversion factor

Step-by-step explanation:

The following conversion factors are valid

1 meter = 100 centimeters

1 mL = 1cm

1 kilometer = 1000 meters

The only conversion factor that is not valid is 1metre = 10millimeter

1meter in millimetres is the same as 10 in 3places not in one place as given in question.

1metres = (10×10×10)mm

1metres = 1000mm

The valid conversion factor is therefore 1m = 1000mm not 1metre = 10mm

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
