Let the number be n.
Then 3n+5 = n+40
Combining like terms, we get
2n = 35, and so n = 35/7, or 17 1/2.

Step-by-step explanation:
A parallelogram<span> is a </span>quadrilateral<span> with two pairs of opposite sides parallel. A </span>square<span> is a </span>rhombus<span> with all the angles equal which has a value of 90°. However, a rhombus is not always a square because it can have different value of interior angles. Hope this answers the question.</span>
Answer:
d. 147 degrees
Explanation:
Please check the picture attached after reading the explanation :)
Assuming that l1 and l2 are parallel, we can identify that the angle at the intersection point of l3 and l2 is the alternate exterior angle of the angle that measures 57 degrees.
This means that that angle also measures 57 degrees.
We can see that l2, l4 and l3 form this little triangle at the corner and we now know that one of its angles measure 90 degrees and the other measures 57 degrees.
In a triangle, the sum of all its interior angles is equal to 180 degrees so we can find the last angle of the triangle by subtracting 90 and 57 from 180.
180-57-90
=33 degrees
A straight lines has an angle measure of 180 degrees as well, so we can find angle x by subtracting 33 from 180.
180-33
=147
Therefore, the measure of angle x is 147 degrees.
I hope this helps!
A composite number is any number that has factors besides itself and 1. In other words, a composite number is a number that you can divide to get a whole number, as long as you don't use the same number or the number 1 to divide it. It's easier to explain with the example above.
Let's work backwards, and start with 21. Can you divide 21 by 1? Obviously, yes, to get 21; but that doesn't count when you're trying to find a composite number. What about 2? That doesn't go in evenly. 3? 21/3=7, which is a whole number. Since it can be divided by a whole number other than 1 or 21, it's composite. See where I'm getting at?
What about 15? 15 divided by 2 isn't a whole number. But 15 divided by 3 is 5, so 15 is composite.
9 can't be evenly divided by 2. But 9 divided by 3 is 3! Another composite number.
What about 2? It can be divided by 1 and 2. But wait a second: 2 is itself! We can only divide 2 into 1 and 2. A number is only composite if it can be divided by something other than 1 or itself, which in this case is 2. So, 2 is NOT a composite number. We actually call it a PRIME number, because it's not composite!
Answer: 2
