Answer:
You can either choose B or D.
Answer:
Step-by-step explanation:
Let's use a start by using common denominators. 
and 
Now, replace the original equation with the common denominators. 
Solve! 
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
Answer:
6%
Step-by-step explanation:
I asked this same exact question, no one got the right answer, so I just guessed, and what do you know, I got the answer right! So here you go.
We know, widest angle is always opposite to the largest side of the triangle, as largest side is 50 here (which is backward to house) so largest angle would be opposite to it. So, that corner will be touched by Fence A & B
"Proportionality Theorem" compares the sides of the same triangle
Here, According to that theorem,
ST / RS = UT / PU
If FG is an altitude, then <DFG is an right triangle.
In short, Your Answer would be Option B
For last question here, remember, longest side must be greater than either side, and must be smaller than sum of those smaller sides.
