What is the fraction?
In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, in a survey, 35 out of 75 students buy a school lunch on Fridays.
35/75
There are 600 students in the school.
Here, 600/75
= 8
Now, 35×8
= 280
Therefore, the cafeteria manager predicted number of students come for lunch at school each Friday is 280.

Combine like terms
2x = 7
Divide both sides by 2
x = 7/2
-2x = 7
step 2. divide both side by -2
-2x = 7
÷2 ÷2
x = -3.5
The answer for 3x - 5x = 3 + 4 is x = -3.5

Allison and her husband Noah both get in their cars and begin to drive at the same time. Allison starts 360 mi from their home and drives directly home at a constant rate of 50 mph. Noah starts at their home and drives away from the home at a constant rate of 40 mph. The system that models this situation is given, where d represents the distance from home, and t represents time, in hours. The solution to the system is (4, 160).
What is the correct interpretation of the solution to this system?
d = 360 - 50t
d =40t
A. Noah will be 160 mi from home and Allison will be 4 mi from home.
B. Allison and Noah will both be 160 mi from home after 4 h.
