Answer:
35 minutes
Step-by-step explanation:
2 hrs 4 min= 160 min
3 hrs 15 min= 195 min
195-160=35
The value of x in terms of b is x = . Therefore the value of x when b = 3 is x = = -1.
We can find both answers by rearranging the equation to get "x =", and then substituting in 3 for b:
-2(bx - 5) = 16
-2bx + 10 = 16
- 10
-2bx = 6
÷ -2
bx = -3
÷ b
x = -3/b, which is the answer to the first part.
To get the second answer, we just substitute b = 3 into this equation and we get:
x = -3/b = -3/3 = -1
I hope this helps!
