If 1 remote control uses 2 batteries
5 remote controls would use 10 batteries.
1x2 = 2
5x2 = 10
If you only had 8 batteries you could only use 4 remote controls as 4x2 = 8

The answer is no, you won’t have enough for all the remotes as you’re 2 batteries short.

anna is on a road trip. she uses 3/4 of a tank of gas every 9/2 hours. How many tanks of gas will anna use after 12 hours?

Answer:

Step-by-step explanation:

This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.

tanks of gas             different tanks of gas          

==========     =         ================

hours                                  different hours.

initial tank of gas = 3/4 tank

initial hours = 9/2 = 4.5 hours

final tanks of gas = X

final time = 12 hours.

Solution

3/4                            x

====         =      ==============

4.5                           12

Cross multiply

4.5x = 12*3/4                      Combine the right

4.5x = 36/4                        Simplify  

4.5x = 9                              Divide both sides by 4.5

x = 9/4.5

x = 2

So she will need 2 tankfuls.

Help please. ASAP.
Alex

Step-by-step explanation:

We can rearrange line M so it is in y = mx + b form.

2y - 10x + 3 = 0 -> 2y = 10x - 3 -> y = 5x -3/2. Since line L and line M have the same slope (which is the m value, 5), they are parallel.

I hope this helps! :)
