-BARSIC- [3]3 years ago

6 0

Answer:

Step-by-step explanation:

3x - 8 > -5 <em>add 8 to both sides</em>

3x > 3 <em>divide both sides by 3</em>

x > 1

2x - 7 < 5 <em>add 7 to both sides</em>

2x < 12 <em>divide both sides by 2</em>

x < 6

From x > 1 and x < 6 we have the solution 1 < x < 6 ⇒ x ∈ (1, 6)

A police car drives with a constant speed of 50 miles per hour. How long will it take to travel a distance of 175 miles?

Evgen [1.6K]

Answer:

It will take the police car 3.5 hours to travel a distance of 175 miles traveling at a rate of 50 miles/hour.

Step-by-step explanation:

If a car is traveling at a constant speed of 50 miles/hour and we wish to know how long it will take it to travel a distance of 175 miles, we will use this formula

d = r*t

Where d is the distance traveled in miles

r is the rate of speed in miles/ hour, and

t is the time in hours

d in this case is 175 miles and r is 50 miles/hour, plugging this in, we have

175 miles = (50 miles/hour) * t Divide both sides by 50 miles/hour

Our miles unit will cancel out, leaving us with

3.5 hours = t

What is the value of 5 in 756

BartSMP [9]

7: has a value of 7 hundreds (or 700)
5: has a value of 5 tens (or 50)
6: has a value of 6 ones (or 6)

5 has a value of 50 or five tens

I believe you would draw this by drawing something that looks like place value blocks. I have attached an example of that. In the ones column, you will have 6 single blocks
