Answer:</h3>
<u>The given quadrilateral are cyclic quadrilateral, so the sum of opposite angle is 180°</u>.
Therefore,
- x + 26° = 180°
- x = 180° - 26°
- x = 164°.
<u>Hence, the value of x is 164°</u>.
I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90
Let be "n" the number mentioned in the exercise.
You need to remember that:
1. In Math word problems:
- The word "times" means multiplication.
- The word "twice" indicates that something is multiplied by 2.
- "Sum" is the result of an Addition.
2. In inequalities, "Less than" is represented with the following symbol:
![](https://tex.z-dn.net/?f=%3C)
Then, based on the above, you know that "3 times a number" can be expressed as:
![3n](https://tex.z-dn.net/?f=3n)
And "Twice the same number":
![2n](https://tex.z-dn.net/?f=2n)
Therefore, "The sum of 3 times a number and twice the same number is less than 45" can be represented with the following inequality:
![3n+2n](https://tex.z-dn.net/?f=3n%2B2n%3C45)
The answer is: Option a.
