Your answer is c, common sense
X=-1 and y=3
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.

8 minutes longer will be the correct answer!
Step-by-step explanation:
First, let's find out how many minutes Gabriella played:
3:32 - 2:49 = 2:92 - 2:49 = 0:43
Check:
2:49 + 0:43 = 2:92 = 3:32
It's correct so...
43 - 35 = 8
Hope this helped!
Answer:
35 + .2m
Step-by-step explanation:
The monthly fee of $35 is a base pay, and you don't change anything with it.
The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
