9x - 1 = -11. Simplify.

zavuch27 [327]

Hi there!

$\large\boxed{x = \frac{-10}{9}}$

9x - 1 = -11

Add 1 to both sides:

9x -1 + 1 = -11 + 1

9x = -10

Divide both sides by 9:

9x/9 = -10/9

x = -10/9

The mass of an electron is approximately 9.11 × 10 -28 grams. Find the mass of 401,000,000 electrons. 3.65311 × 10-19 grams 3.65

NNADVOKAT [17]

Answer:

$Total\ Mass = 3.65311 * 10^{-19}$ grams

Step-by-step explanation:

Given

$Mass = 9.11 * 10^{-28}g$

Required

Determine the mass of 401,000,000 electrons

To do this, we simply multiply the mass of 1 electron by the number of electrons.

This gives:

$Total\ Mass = 401,000,000 * 9.11 * 10^{-28}$

$Total\ Mass = 3653110000 * 10^{-28}$

Express 3653110000 as a standard form

$Total\ Mass = 3.65311 * 10^9 * 10^{-28}$

Apply law of indices:

$Total\ Mass = 3.65311 * 10^{9-28}$

$Total\ Mass = 3.65311 * 10^{-19}$

Hence, the mass of 401000000 electrons is $3.65311 * 10^{-19}\ grams$
