Answer:

120 mph

Step-by-step explanation:

Distance = rate * time

D = 70 miles

t = 35 minutes

So that gives us:

70 mi = r(35 min)

Divide both sides by 35 min:

70/35 mi/min = r

simplify:

2 mi/min = r

If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:

2 * 60 = 120

120 mph = r

6. If b&gt;6, then 3b + 3 could be<br> A. 18<br> B. 19<br> C. 20<br> D. 21<br> E. 22
Gala2k [10]

Answer:

E. 22

Step-by-step explanation:

Hello!

We know that b>6, and we are asked to find the possible values for 3b + 3.

Let's directly substitute 6 for b:

  • 3(6) + 3
  • 18 = 3
  • 21

Now, because b is greater than 6, and not equal to 6, any value greater than 21 will work.

The correct option is E. 22.

What does it mean by n? thanks
ra1l [238]
When you solve the inequality, you will write down all the x values that satisfy the inequality but they have to be integers. The n is x, it is just a common variable used to help describe what kind of numbers they want.
