Answer:
10 ( 12p - 6k)
Step-by-step explanation:
4p x 3 = 12p
2k x 3 = 6k
you cannot subtract 12p and 6k bcuz they do not have the same variables.
The tens place will be where the zero is which the value would be 70 since the 7 is in the thousand place the value is 7,000
Answer:
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Step-by-step explanation:
f(x) = -3x² +30x - 71
f(x) = -3(x² +-10x) - 71
f(x) = -3(x² +-10x+5^2-5^2) - 71
f(x) = -3(x² +-10x+5^2) -3(-5^2) - 71
f(x) = -3(x² +-10x+5^2) + 4
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
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.
