To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2. First answer, 3^2+5^2=c^2. Solve for c. c=5.83. The second answer, 3^2+b^2=5^2. Solve for b. b=4.

Answer: $556.50
Step-by-step explanation: 6% of 525 is 31.5 so 525 + 31.5 = 556.50$
1 5/6 + 2 1/5
3 + 5/6 + 1/5
3 + 25/30 + 6/30
3 + (25 + 6) / 30
3 + 31/30
3 + 1 1/30
4 1/30
The answer is: 4 1/30 or 4.0333.
5x+y=2
4x+y=4
5x+y=2
-1( 4x+y=2)
5x+y=2
-4x-y=2
your y'all cancel out so you r left with
x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12
Answer: x = -2 y = 12
there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that
