Answer:
x = 10; x = 0
Step-by-step explanation:
x < 29 means x is less than 29. Any number less then 29 is a solution.
For example, pick x = 10. Since 10 < 29, x = 10 is a solution. How do we know x = 10 is a solution?
We start with x < 29.
Now replace x with 10.
10 < 29
Since 10 < 29 is a true statement, then x = 10 is a solution.
Now pick another number less than 29. For example, oick 0.
x = 0 is a solution.
Proof:
x < 29
Replace x with 0:
0 < 29
Since 0 < 29 is a true statement, then x = 0 is a solution.
You can give more solutions just by picking any numbers that are less than 29, such as 1, 2, 3, 15, 28, 23, -5, -18, etc.
Answer: x = 10; x = 0
The man invested 1/5 of the money at 4/100. Which says he earns 4/500 of his total money on one month.
He also invested 1/2 of the money at 5/100. Which means he earns 5/200 of his total money per month.
For the last part, he spent the rest of the money which is: x + 1/5 + 1/2 = 1
Make the denominators equal: x + 2/10 + 5/10 = 10/10
Add like terms: x + 7/10 = 10/10
Substract 7/10: x=3/10
He gave this money for 3.5/100 interest. Which equals 10.5/1000 of his total money.
When you add the three values: 4/500 + 5/200 + 10.5/1000
Make denominators equal: 8/1000 + 25/1000 + 10.5/1000
Add the like terms: 43.5/1000
This means the man's money's 43.5/1000 is equal to $870
Set the values equal: 43.5x/1000 = 870
Make the denominators equal: 43.5x/1000 = 870,000/1000
Multiply with 1000: 43.5x = 870,000
Divide both sides by 43.5: x = 20,000
The man's total money is $20,000
Answer:
He pays taxes on the amount after the discount. So 10% of $40.50 versus $45.
Step-by-step explanation:
10% on $40.50 = $4.05
10% on $45.00 = $4.50
