The question asks for the length of CD and HJ. To find those, we need to find a connection between them.
In the given statement, it says ABCD ≅ FGHJ. When we look at the equation, the corresponding letters are equal. For example, angle A is congruent to Angle F. Or BC ≅ GH.
So we know that CD and HJ are congruent.
Set them equal:

Subtract 2x from both sides:

Subtract 2 from both sides:

If x is 3, plug it in:

Simplify:

So, HJ is 11. And because HJ ≅ CD, CD is 11 too.
Answer:
Wavelength
Step-by-step explanation:
The picture below is an example of a wavelength which is very similar.
Answer:
5x + 9y ≤ 32
Step-by-step explanation:
Each cassette tape costs $5 and each CD costs $9
Let x represent the number of tapes and y the number of CDs.
The cost of the cassettes is the number of cassettes times the cost per cassette and the cost of the tapes is the number of tapes times the cost per tape. We add these together to get the total cost. The total cost must be less than or equal to 32
32≥5x+9y
Answer:
Yes.
Step-by-step explanation:
Any number less that 0, when multiplied by a positive number, will make it a negative number.
