Answer:
k = 4
Step-by-step explanation:
Step 1: Write equation
-3k - 9 = -21
Step 2: Solve for <em>k</em>
- Add 9 to both sides: -3k = -12
- Divide both sides by -3: k = 4
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-3(4) - 9 = -21
-12 - 9 = -21
-21 = -21
Answer:
Therefore, the correct answer is 24,069,100.
Step-by-step explanation:
(6.91 x 10^4) = 6.91 x 10,000 (10 x 10 x 10 x 10) or 69,100.
(2.4 x 10^7) = 2.4 x 10,000,000 (10 x 10 x 10 x 10 x 10 x 10 x 10) or 24,000,000.
24,000,000 + 69,100 = 24,069,100
Therefore, the correct answer is 24,069,100.
