Answer:
2.69≤x≤17.31
Step-by-step explanation:
Lety the amount in the other Piggy bank be x.
The difference in the amount of money between the two banks is no more than $10 is expressed as;
|x-7.31| ≤ 10
The value in the modulus sign can be positive or negative
If positive;
x-7.31 ≤ 10
x ≤ 10+7.31
x≤17.31
If negative
-(x-7.31) ≤ 10
-x+7.31 ≤ 10
-x ≤ 10-7.31
-x ≤ 2.69
Multiply both sides by -1
x ≥ -2.69
The compound inequality representing the amount of money in the other bank is -2.69≤x≤17.31
I do not know what you mean by the wording of some of these questions, so I will just give you the formula and tell you how to apply it. The formula of the Pythagorean Theorem is a^2 + b^2 = c^2. a and b are the two sides adjecent to the right angle (in the corner). c is the side opposite the right angle. So, to get c you would have to add sides a and b but with each of them to the second power. Then, you would find the square root of the sum (you can do this with a calculator). To find sides a or b, subtract a or b (whichever one available) to the second power from c to the second power. Then find the square root of the sum. That is all I know how to do, so combine this knowledge with yours to see if you can solve it. If you have any questions about what I already know, feel free to ask. You can also ask for an example. If you have a question about something that I have not explained, look it up on the internet, or hopefully you can find someone who can help you. I hope this helps.
