The answer is C- Berthas cake weighs 463 grams more than Jessups cake
Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.
Given:
In triangle
.
To find:
The value of y.
Solution:
In a right angle triangle,

In triangle BGU,



Isolating y, we get



Therefore, the correct option is A.
