Answer:
22
Step-by-step explanation:
64+20= 84 (number of students in total)
84/2= 42 (number of students each session)
Moving 22 students to Monday will result in equal number of students.
Question:- Alana biked 12 miles in 48 minutes. What is Alana's speed in miles per minute?
Answer:-
Set up a proportion.
12/48 = 1/x
Cross multiply.
12*x = 12x
48*1 = 48
12x = 48
12x/12 = 48/12
x= 48/12
x= 4
Now, we have our final answer. x = 4
Final answer:- Alana bikes 4 miles per minute.
Answer:
It's choice B.
Step-by-step explanation:
When r= -11,
x^2 + 8x - 33 = (-11)^2 - 88 - 33
= 121 - 88 - 33
= 0
- so x = -11 gives a zero value and is a solution to the equation.
B - 45 because 27 divided by 6 is 4.5 and then 10x4.5=44
Answer:
sqrt(20)
Step-by-step explanation:
The two perpendicular side lengths are equal, so using Pythagoras theorem:
x = sqrt( sqrt(10)^2 + sqrt(10)^2 )
x = sqrt(10 + 10)
x = sqrt(20)
