Answer:
85 messages
Step-by-step explanation:
The system of equations for this is
35 + .10x
18 + .3x
where x = the number of text messages
Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.
When you plug in 85, or x = 85, you get 43.5 for both equations because
35 + .10(85) = 43.5 18 + .3(85) = 43.5
Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

4. B is the answer
5. A is the answer ( y is the same , x are the opposite)
6. C
7. D
Below = a negative number (-)
-2
up = positive number
5
the equation would be -2+5 = ?
and the answer/ integer that represents the new location is 3
