Answer:13
Step-by-step explanation:
Answer:
x=-1, y=2
Step-by-step explanation:
Given:
2y=6x+10
y=2x+4
Substitution for y into first equation:
2(2x+4)=6x+10
4x+8=6x+10
0=2x+2
2x=-2
x=-1
y=2(-1)+4
y=2
Again set a proportion
x/4=35.25/1
=x=4(35.25)
x=141
Therefore the boat traveled 141 kilometres.
The answer is C.
