Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
The answer is that x is equal to 0.17 or -5/-28. You have to add like terms so 25x+2=53x-3 will turn to -28x=-5.
Answer:

Step-by-step explanation:
Answer:
the total distance walked is 20 km
Step-by-step explanation:
The computation of the total distance he walked is shown below:
Let us assume the total distance walked be d
Now the total time would be
Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25
d ÷ 16 + d ÷ 10 = 3.25
(5d + 8d) ÷ 80=3.25
13d = 260
d = 20 km
Hence, the total distance walked is 20 km
Your answer is A. 7.2x10^-5
