Hi there! The answer should be a = 5. I have included an image with the process. Hope this helps for future reference!

P.S. It is okay with me if you save the image for help later. :)

Answer:

a = 5

Step-by-step explanation:

3(a - 4) + 1 = 9 - a Distribute the 3 into a-4

3a - 12 + 1 = 9 - a Combine like terms

[-12 and 1]

3a - 11 = 9 - a Add 11 to both sides to isolate 3a

+11 +11

3a = 20 - a Add a to remove it and have all a

+a +a

4a = 20 Divide by 4 to only have a

/4 /4

a = 5

(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?

kramer

Answer:

5 miles = 75 minutes

Step-by-step explanation:

We know that:

3 miles = 45 minutes

Solution:

3 miles = 45 minutes
=> 1 mile = 45/3 minutes
=> 5 miles = 45/3 x 5
=> 5 miles = 15 x 5
=> 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.
