Let m represent the number of miles this guy runs in a day.
He runs every day, so the minimum number of miles has to be greater than 0.
According to the problem statement, the max number of miles is 3.5 miles or less.
Translate this into a (symbolic) inequality.

Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
Answer:
215 minutes
Step-by-step explanation:
Let
Number of days she rode for 35 minutes = x
Number of days she rode for 55 minutes = y
Total time spent riding her bike = 35x + 55y
x = Monday + Wednesday + Saturday
x = 3 days
y = Tuesday + Thursday
= 2 days
Substitute into the equation
Total time spent riding her bike = 35x + 55y
= 35(3) + 55(2)
= 105 + 110
= 215 minutes
