Answer:
7
Step-by-step explanation:
28 divided by 4 is 7
You would subtract 6 from both sides in order to get m by itself. When you do this you get m=-10
9.8t^2-49t+40=0
t=(49±√833)/19.6
t≈1.027, 3.97
1.027<t<3.97
Answer:
x>1/2
Step-by-step explanation:
6x>3
x>1/2
50-x^2=0
Move the x^2 to the other side
x^2=50
Now take the square root of both sides
x=+_(50)^1/2 (^1/2 means square root)(+_ is plus or minus. Sorry XD)
Now simplify the square root
X=+_5(2)^1/2
Voila. The answer is C
