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:
Express 3653110000 as a standard form
Apply law of indices:
Hence, the mass of 401000000 electrons is

- Equation 2: L + M = 45
Explanation:
Rewrite the question to delete the typos:
- Lindsay is 5 years younger than Mark. Seven years ago, the sum of their ages was 31. Let l be Lindsay's age and let mmm be Mark's age.Which system of equations represents this situation?
<u>1. Name your variables:</u>
<u />
<u>2. Translate each verbal statement into an algebraic expression:</u>
a) Lindsay is 5 years younger than Mark
- L = M - 5 ← first equation
b) Seven years ago, the sum of their ages was 31
L + M - 14 = 31
L + M = 31 + 14
L + M = 45 ← second equation
<u>3. Write the two equations:</u>
System:
- Equation 1: L = M - 5
- Equation 2: L + M = 45
The answer is .900,
.(tens)(hundreds)(thousands)
