Step-by-step explanation:

<u>Step 1: Write the equation</u>

(12.2a + 9.7b) – (18.1b – 0.2a) – (6.7a + 6.8b)

<u>Step 2: Open all brackets</u>

12.2a + 9.7b - 18.1b + 0.2a - 6.7a - 6.8b

<u>Step 3: Arrange all 'a' together and all 'b' together</u>

12.2a + 0.2a - 6.7a + 9.7b - 18.1b - 6.8b

<u>Step 4: Simplify</u>

5.7a - 18.2b

A large railroad car is filled with 1745 gallons of milk. The car springs a leak in the bottom, and milk starts dripping out at
jeka57 [31]

Answer:

585.98 miles

Step-by-step explanation:

We need to convert 1745 gallons to mL.

We know 1 gallons = 3785.41 mL

So 1745 gallons = 1745 * 3785.41 = 6,605,540.45 mL

Leaks are at 204.84 mL/sec, so it will take:

6,605,540.45/204.84 = 32,247.32 seconds

In hours, that is:

32,247.32/(60*60) = 8.96 hours

Now, since train is travelling at 65.4 miles per hour, in 8.96 hours, train will approximately travel:

65.4 * 8.96 = 585.98 miles
