Use Substitution to solve the following System of Equations.<br> y = 2x - 4<br> y= 12 +3
castortr0y [4]

Answer:

x = 9.5

this should be the right answer if the same one you had to solve.

Step-by-step explanation:

y = 2x - 4

y = 12 + 3                             combine them

2x - 4 = 12 + 3

    +4         +4                   The 4's cancel each other out

2x = 12 + 7                     Add then divide

 2x = 19

  2x = 19

  ----   ----

   19   19

 x = 9.5

URGENT PLEASE HELP. A radio signal travels at 3.00 * 10^8 meters per second. how many seconds will it take for a radio signal to
lbvjy [14]
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.


3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.

3.54/3=1.18
10^7/10^8=1/10

Now we just multiply our answers together because we separated them before we divided.

1.18*1/10=.118

So the answer is .118 seconds
