2. Read the problem below: The average distance from the sun to the planet Mercury is about 60,000,000 km. The diameter of a human hair is about 0.0025 cm. (a) What is the distance from the sun to Mercury written in scientific notation? 60,000,000km-6x1047km (b) What is the dianeter of a human hair written in scientific notation? 0.0025cm-2.5x10^-3 (c) Bonus Question - To subtract the measurements in Parts (a) and (b), what do you have to do first?

answer: i don't understand. what are the options

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
