3
Step-by-step explanation:
It’s A, if you add 70 and 65 you get 135 and 180-135=45 :)
Answer:

Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is the y intercept
We'll find slope first.
slope formula is

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.
So we just put the given values into our equation.

Simplify

Now we put this into our y=mx+b
y=0/-3x+b
now we need the (b)
to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.


Solve
1=0+b
b=1
Put this in our formula

x + y = 52
x = y - 18
Adding,
2x + y = 52 + y - 18
2x = 34
x = 17
y = x + 18 = 35
Check: x+y = 17+35 = 52, good
Answer: 17 and 35
