Answer:
y=6
Step-by-step explanation:
|10-5y|=20
Since the absolute value is isolated, we can then separate the equations
For absolute values, there is a positive and negative when we remove the absolute values.
10-5y = 20 10-5y= -20
Subtract 10 from each side
10-10-5y = 20-10 10-10-5y= -20-10
-5y = 10 -5y = -30
Divide by -5
-5y/-5 =10/-5 -5y = -30/-5
y =-2 y =6
From the question, we can create the equation
57.8 = 23.5 + 18.3 + 5.7 + x
This equation says that the total distance traveled (57.8 km) is equal to all the distances she drove, plus the final distance back home.
Solving for x, we get that x = 10.3 km
