The train goes 2 miles per hour.
The amount needed is 12 miles.

Your answer would be 6 hours

Answer:

Emily is 17

Step-by-step explanation:

If Jamie is 47 and she is 4 less than 3 times older than Emily, you want to start by doing the opposite of each identifying word. Remember to work backwards. 4 less means minus 4, but you want to do the opposite so you will add 4 to 47. 47 + 4 = 51 Then if it says 3 times this mean multiplication but again, we wanna do the opposite so 51 ÷ 3 = 17

To check it Multiply 17 by 3 and then subtract 4. 17*3=51 51-4=47

This is a tough one. Thanks to everyone who helps
VladimirAG [237]

Step-by-step explanation:

Hello there!

A good first step is to fill the t=blanks with 2 and 4.

Then proceed as follows:

3 |2x+4|=24\\3(2x+4)=24\\2x+4=\frac{24}{3} \\2x+4=8\\2x=8-4\\2x=4\\x=2

And there you are! Feel free to comment with questions, and have a grwat day!
