write out the equation:
8y=3+7y (I'm assuming y is the amount of comic books)
8=3+7
8=10
Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.
The answer to the question
Answer: No
Step-by-step explanation: you have to subtract 60$ and 15% and then subtract 45$ and 10%. Equals 35$ the total cost.
Given:
The measures of the angles in a triangle are in the ratio of 2:2:4.
To find:
The exterior angle that is adjacent to the largest angle.
Solution:
Let the interior angles of the triangle are 2x, 2x and 4x respectively.
According to the angle sum property, the sum of interior angles of a triangle is 180 degrees.




Clearly, x=22.5>1, so 4x is the largest angle between 2x, 2x and 4x.
Now,



Let the required exterior angle that is adjacent to the largest angle be y.
Interior angle and adjacent exterior angles are supplementary, so their sum is 180 degrees.




Therefore, the exterior angle that is adjacent to the largest angle is 90°.
