Answer:
t = - 1/8
Step-by-step explanation:
t ÷ 5/12 = - 3/10
t × 12 ÷ 5 = - 3/10
12t/5 = - 3/10
12t × 10 = -3 × 5
120t = - 15
t = - 15/120
t = - 1/8
Thus, t divided 5/12 = - 3/10 => -1/8

Answer:
y stands for unknown number
Step-by-step explanation:
 
        
             
        
        
        
Solve the system by graphing  
{y = 7 - x   the slope is -1 and the y intercept is 7
{x + 3y = 11   3y = -x+11  y = 1/3 x + 11/3  the slope is 1/3 and the y intercept is 11/3
The solution is x=5, y=2   you will need to graph
Classify the system without graphing
{2x + y = 3      y = -2x+3      
{y = -2x - 1
These lines are parallel   same slope different y intercept
C) Inconsistent System
Classify the system without graphing  
{x + 3y = 9
{-2x - 6y = -18   divide by -2
x+3y = 9
same line
A) Dependent System
