A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.
Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.

Answer:
Expression B
Step-by-step explanation:
<em>Let us find the information in the question</em>
- Alejandro has gon to school of the last 35 days
- We need to find the expression that represents the number of days Alejandro has gone to school.
<em>We must write the given information in an expression then look for it in the choices.</em>
∵ He has gone of 35 days
→ "of" means times (×)
∴ The days that he has gon = 35 ×
<em>The expression that can be used to determine the number of days he has gone to school is</em> 35 ×
The choices are:
A)
B) 35 ×
C) ÷ 35
D) ÷ 35
The answer is B
Answer:
x=4
Step-by-step explanation:
here's our equation: 3x=x+8
Our goal: to isolate x onto one side with nothing else on that side.
x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides
2x=8
Now we can divide by 2
x=4
Hope this helps! :)
