The cafeteria manager predicted number of students come for lunch at school each Friday is 280.
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.

In a recent golf match, Tiger’s score was 4 less than Phil’s score. Their combined scores totaled 140. Let p represent Phil's score and t represent Tiger's score.
Which pair of equations can be used to determine their scores?
A. p – t = 140
p + t = 4
B. p + 140 = t
p = 4
C. p + t = 140
p – t = 4
D. p + t = 140
p + t = 4
(i think this one is C)

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.
C. Noah will be 4 mi from home and Allison will be 160 mi from home.
D. Allison and Noah will both be 4 mi from home when they drive for 160 min.

please help me I dont understand these.
Ok the first thing I recommend you doing is making a formula.
Next you should plug in the numbers.
Then you will have another formula.
p=1250
so....
n=how much is needed.
He need's $125 to complete the money needed to buy his computer
Hope I helped. :)
