Locate and label the following fraction on the number line 1/2 4/2 5/20             1                 2               3

Answers


1/2 would be in between 0 and 1. The fraction 4/2 is actually 2, so it would just be plotted on the number 2 on the number line. 5/2 is reduced to 2.5, therefore it goes in between 2 and 3.
0, 1/2, 1, 2 (4/2), 5/2, 3
1/2 = 0.5 and 0.5 is > than zero but < than one
4/2 is 4 divided by 2 = 2 and two is 2 (Funny)
5/2 = 2 and 1/2 = 2.5

2/3x - 7 = 11 answer is x=27 how do you get that answer

Answers


In an  algebra problem, you don't set the answer-goal and say "Go for it!"

There is only one correct answer, so the only appropriate way to go about it is to say "Here is the equation.  Find the solution.?"

Maybe 27 is the solution, and maybe it's not.
We're about to find out.

You said                        2/3 x - 7  =  11

Add  7  to each side:      2/3 x      =  18

Divide each side by  2 :  1/3 x      =  9

Multiply each side by  3 :     x      =  27 .

So yes, the correct solution is 27.  And that's how to find it.

A truck driver drove 300 miles in 6 3/4 hours. How many miles per hour did the driver drive?

Answers

44.4 miles per hour. You just divide 300 and 6.75 (Think as the 3/4 as quarters each 1 is .25)  then you will get 44.4. To check your answer you would multiply 44.4 and 6.75 and get 299.7. This is not 300 but when you round that .7 to the nearest 10 you will get 300. Hope this helped.

Answer:

44.44 miles per hour.

Step-by-step explanation:

A truck driver drove 300 miles in 6(3)/(4) hours.

We have to calculate the speed per hour.

First we convert 6(3)/(4) hours to decimal form.

6(3)/(4) = 6.75 hours

∵ in 6.75 hours the driver drove = 300 miles

∴ in 1 hour he drove = (300)/(6.75) miles

                                = 44.44 miles

The truck driver drove 44.44 miles per hour.
