Athermometer measures temperature to the nearest 0.5°c which measurement shows an appropriate level of precision for the thermometer. a.21.55°c b20°c c.16°c d16.0°c

The temperature which has best degree of precision would actually be the temperature reading which has similar decimal place with the error. So the best answer would have 1 decimal and from the choices above, this would be:

D. 16.0°C

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
