Step-by-step explanation:
<u>Step 1: Define</u>
3n - 5 = 22
<u>Step 2: Solve for </u><em><u>n</u></em>
- Add 5 to both sides: 3n = 27
- Divide 3 on both sides: n = 9
Option A
The simple interest earned is $ 105
<em><u>Solution:</u></em>
Given that, $300 at 5% annual interest for 7 years
Therefore,
Principal = $ 300
Rate of interest = 5 %
Number of years = 7
<em><u>The simple interest is given by formula:</u></em>

Where,
p is the principal
r is the rate of interest
n is the number of years
<em><u>Substituting the values in formula,</u></em>

Thus simple interest earned is $ 105
If the length of the shape is 28 and the segment above it is 8 and is the same size as what’s left over of x, all u need to do is take 8 away from 28. Therefore 28 - 8 = 20, which means x = 20.
