I think it is 6n-8. But I could be wrong these are tricky to get. Good luck
Answer:
You got them both right, no other choices need to be selected.
Step-by-step explanation:
Both the choices you have put yes to, will give an answer equal to 32.
Since they want us to find the full amount of students in his class, and 20 is 4 more than half the class 20-4=16 and then 16 x 2 is 32
1/2m+4=20 is correct because, if you move the 4 across the equal sign it become a negative and will be subtracted from the 20 therefore becoming 16. 1/2m=16. Now left with only the 1/2m we must multiply by 2 because 1/2 is a fraction and mutipliting it by 2 will allow us to get 1/2 to equal 1 and m by itself.
1/2m*2=1m
1m=16*2 Keep in mind you must do the same to both sides so the 16 is multiplied as well.
4th option: Same thing different order
Just send 1/2m over equal sign and 4 over the equal sign to trade places. and you will have 1/2m=16
Answer:
they have different ways to find there awnsers
Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:
In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:
So
The force on the book is 250N.
Answer:
3q + 2p
Step-by-step explanation:
q + p + q + p + q = 3q + 2p
