You buy 7 books
3b+5=26
*subtract 5 to the 26 side*
3b=21
Now divide 21 by 3
B=7
So there are 7 books bought. ^^
Answer:
Yermin. √0.5 will be at Yermin's point
Step-by-step explanation:
Say Pedro line point is 0.25

Factors are the numbers you multiply together to get given number.
All possible factorizations of number 18 by two factors are:
- 18=1·18;
- 18=2·9;
- 18=3·6.
Answer: 1 and 18, 2 and 9, 3 and 6.
For this case we have the following expression:
![4x + 2 (2x-5) - (3-5x)](https://tex.z-dn.net/?f=4x%20%2B%202%20%282x-5%29%20-%20%283-5x%29)
Applying distributive property to the terms within parentheses taking into account that:
![- * + = -\\- * - = +](https://tex.z-dn.net/?f=-%20%2A%20%2B%20%3D%20-%5C%5C-%20%2A%20-%20%3D%20%2B)
We have:
![4x + 4x-10-3 + 5x =](https://tex.z-dn.net/?f=4x%20%2B%204x-10-3%20%2B%205x%20%3D)
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
![4x + 4x + 5x-10-3 =\\13x-13](https://tex.z-dn.net/?f=4x%20%2B%204x%20%2B%205x-10-3%20%3D%5C%5C13x-13)
Thus, an equivalent expression is:
![13x-13](https://tex.z-dn.net/?f=13x-13)
Answer:
![13x-13](https://tex.z-dn.net/?f=13x-13)
