Answer:
2.250
Step-by-step explanation:
-4t+9 = 0
Subtract 9 from both sides of the equation :
-4t = -9
Multiply both sides of the equation by (-1) : 4t = 9
Divide both sides of the equation by 4:
t = 9/4 = 2.250
t=2.25
You want to find out what t is.
If 4t = 9, the how much is t?
First step is to divide 9 by 4.
When you divide 9 by 4, you find out how much t is.
When you divide 9 by 4, you get 2.25, or 2 1/4
$4
