The answer to your Q the better one it is the 4- pound bag because it coast less money
Answer:
b = 
Step-by-step explanation:
Given
a = 4b +
- b, that is
a = 3b + 
Multiply through by 3 to clear the fraction
3a = 9b + 2 ( subtract 2 from both sides )
3a - 2 = 9b ( divide both sides by 9 )
= b
The total is 219 miles.
He rides at 38 mph and walks at 4 mph for 8 hours. If he rides for h hours, he walks for 8-h hours.
Set them equal to each other:
219=38h+4(8-h)
Solve and you should get 5.5 hours on the bicycle and 2.5 hours walking.
