Answer:
Ben had biked 8 miles
Step-by-step explanation:
You would need to take 12 and divide it by three . That would make 4. After that you would take 4 and multiply it by 2 since he rode 2/3 miles of 12. Then you would end up with 8.
I believe the answer is d.
Answer:
A3-a-c=b assuming you mean A=
Step-by-step explanation:
Basically, we'll be using properties of equalities to "balence out the equation" and shift all variables except for b to one side
1) Use multiplication prop. of equality
This property states that if we multiply one side we must multiply the other. We'll be doing this for the "3" portion.
3(A)=3((a+b+c)/3)
3A= a+b+c
2) Use subtraction prop of equality
This one states that if we subtract one side we must subtract the other. We will be doing this for the "a" and "c" portion
(3A)-a=(a+b+c)-a
3A-a=b+c
(3A-a)-c=(b+c)-c
3A-a-c=b
Hopefully that helps a bit T_T
Answer: C, It stays the same.
Step-by-step explanation: If you simplify the ratio (the fraction) by canceling the t's, you get 2/1 or 2:1. This means that no matter the value of the variable t, the value of the expression will stay the same.
Answer:
x = 8
Step-by-step explanation:
4x + 112 = 9x + 72
-112 -112
4x = 9x - 40
-9x -9x
-5x = -40
----- --------
-5 -5
x = 8
