Step-by-step explanation:
Since we have given that
Investment of $3,000 at 5% simple interest for 20 years
.
Simple interest would be

Investment of $1,000 at 16% simple interest for 20 years
Simple interest would be

Investment of $3,000 at 16% simple interest for 2 years.
Simple interest would be

Hence, Third investment is the least simple interest and Second investment is the most earned simple interest.

Answer:x =2
Step-by-step explanation:
Let's translate your words into numbers and fractions. So it's
5/4 - 1/x - 2 = -4/-4.
Let's Simplify it first by eliminating -4/-4, the answer will be 1 since negative divided by negative is positive and 4 divided by 4 is 1.
5/4 - 1/x - 2 = 1
Then Get the GCF of the equation which is 4x.
Then divide the whole equation by 4x and it would be,
<span><u>5/4 - 1/x - 2 = 1
</u></span> 4x
Then it will look like this, 5x-8x-4 = 4x
Then transpose, 5x - 8x - 4x = 4
Simplify by deducting the left side. -7x = 4
Then divide both sides by -7.
Then the final answer would be x = -4/7
