Look at the picture.
The equation:
10x - 15 = 6x + 9 <em>add 15 to both sides</em>
10x = 6x + 24 <em>subtract 6x from both sides</em>
4x = 24 <em>divide both sides by 4</em>
<h3>
x = 6</h3>
-400 dollars as it it the lowest amount of money
Simple interest = $769
Principal = $6000
Rate = ?
Time = 10 months (must convert to years if in months) = 10/12 = 0.833
Formula
I = prt
Substitute
769 = 6000 × r × 0.833
769 = 4998r
Divide both sides by 4998
769/4998 = 4998r/4998
0.15386 = r
(to the nearest tenth of a percent) = 0.15
Therefore, your rate is 0.15%.
Answer:
given the sun has risen every day for the last 5000 years — or 1,826,213 days — the probability it will rise tomorrow is 1,826,214 / 1,826,215. which is 99.9%
