Total: 195 = x + (x+25)
195 - 25 = 2x
170 = 2x
85 = x

Answer:
The answer is D. 29.64
Step-by-Step Explanation:
Parenthesis first...
39.64-5*(2)
Then multiplication...
39.64-10
Then subtraction...
29.64
The point slope equation would be one of the equations with -10 in front because it multiplies into x as the negative 10 slope. That narrows it down to C and D. Then the points show 1 and 4 and it has to be positive. That narrows it down the answer D. If this is right could you possibly give me brainliest? Hope this helped.
The answer will be B) 42%
