Answer:
The answer is 829 because you are adding
Step-by-step explanation:
Let,
Lee’s class size = L
Fred’s class size = F
We are told that Lee’s fifth-grade class has 1.0 times as
many students as Fred’s
Therefore, L = 1F
L = F
Question A. If there are a total of 60 students, how many
students does Fred’s class have?
Total number of students = 60
L + F = 60
Since L = F
L + F = F + F + 60
F + F = 60
2F = 60
F = 60/2
F = 30
Therefore, if there are a total of 60 students, Fred’s class
has 30 students.
QUESTION B. If there are a total of 60 students, how many
students does Lee’s class have?
Total number of students = 60
L + F = 60
Since L = F
L + F = L + L + 60
L + L = 60
2L = 60
L = 60/2
L = 30
Therefore, if there are a total of 60 students, Lee’s class
has 30 students.
Answer:
the answer is 12 attendees
Step-by-step explanation:
Let a=the attendees & Let d=the cost
if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d
d=7a+13
97=7a+13
now take subtract 13 from both sides
97-13=7a+13-13
since the 13 cancels out on the right side it'll now read:
84=7a
to get a by itself you now divide 7 from both sides getting a by itself
84/7=7a/7
12=a
so the answer will be 12
