Answer:
b= -164
Step-by-step explanation:
calculate the difference
7x(-75)-2b= -197
multiply the numbers
-525-2b= -197
move the constant to the right- hand side and change the sign
-2b= -197+525
add
-2b=328
divide
b= -164
I divided 50 miles by 2 = 25 miles (walked) 25 miles (horseback)
I divided 25 by 3 = 8.33
I divided 25 by 9 = 3
Added together = 8.33 + 3 = 11.33
So time to complete the journey 11.33 hour
