Answer:

50 mph, 450 mi, 73.3 ft/sec

Step-by-step explanation:

Part 1:

Find the unit rate (which here is mph).

 175 mi

------------- = 50 mph

3.5 hrs

Part 2:

In 8.5 hrs, the Andersons can expect to cover (50 mph)(8.5 hr) = 425 mi

Part 3:

50 mph       88 ft/sec

------------ *  ----------------- = 73.33 ft/sec, or 73.3 ft/sec to the nearest tenth.

      1              60 mph

Step-by-step explanation:

First, you should replace the variables with the numbers. So,

2(6)-[6-(4+2)/6]

Don't worry, it'll look less confusing later! Next, solve the parentheses that are in the very middle.

2(6)-[6-6/6]

2(6)-[6-1]

12-5

zysi [14]

Answer:

n-7=13

Step-by-step explanation:

We need to find an equation that represents the expression: "Seven less than a number is thirteen".

It means that a number minus 7 equals 13. So, the correct option is: n-7=13

Bonus: Solving for 'n' we have that n=20.

So, Seven less than 20 equals 13!!
