James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.
Answers
Answer:
3
Step-by-step explanation:
65-23= 42
42/14= 3
Answer:
14x+23 =65 x=3CDs
Step-by-step explanation:
So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.
To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

A triangle formed by the sides 3.8cm ,3.7 cm, and 5cm is
Answers
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.
The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.
How to find the type of triangle?
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,
For a triangle to be right angle triangle,[tex]c^2=a^2+b^2[/tex]
By this law it is observed that,
For a triangle to be acute angle triangle,[tex]c^2<(a^2+b^2)[/tex]
For a triangle to be obtuse angle triangle,[tex]c^2>(a^2+b^2)[/tex]
The sides of the given triangle are 3.8 cm ,3.7 cm, and 5 cm.
Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,
[tex]c^2=5^2\\c^2=25[/tex]
Other two sides,
[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]
Therefore,
[tex]25<28.13\\[/tex]
Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

Cnidarians are another major group of invertebrates. Jellyfish, coral, hydra and anemone are examples of cnidarians. They have soft bodies and no heads. They have stinging tentacles that they use for defense and to capture prey. Cnidarians have radial symmetry. That means that their parts are arranged around a center. If you were to draw a line to cut them in half in any direction, the two sides will always match. Radial symmetry is often a characteristic of more simple animals than bilateral symmetry, where there is only one line you could draw to make two sides match. With bilateral symmetry, different body parts may have different functions. With radial symmetry, the entire body may perform all life functions.
Jellyfish do not have (what?)
a. heads.
b. tentacles.
c. symmetry.
d. soft bodies.
Answers

Given hexagon LMNOPQ is congruent to hexagon L'M'N'O'P'Q'. What is the measure of OP?
6 in
7 in
45 in
51 in
Answers
Answer:
51in
Step-by-step explanation:
Just set the equations of line OP and line O'P' equal to one another, then solve for x.
ie: 3(2x+3)=(8x-5)
To solve for x, distribute first. Then, subtract 6x from each side. Then, add 5 to each side.
ie: 6x+9=8x-5
ie: 14=2x
Now divide by 2.
ie: 7=x
Now that you have your x value, plug it back into one of the equations and solve for the measure of line OP. To check you answer, plug 7 for x into the equation where they are set equal, then solve them both and if the end result is true (51=51) it is correct.
