Answer: 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.

It's "too short", but there's not much else to say here.
Answer:
4.27985 and 14.72015
Step-by-step explanation:
4.27985 x 14.72015 = 63
4.27985 + 14.72015 = 19
Answer:
5x - 2y = - 2
Step-by-step explanation:
Given the 2 equations
- 2x + y = 0 → (1)
- 7x + 3y = 2 → (2)
Subtracting (2) from (1) term by term
- 2x - (- 7x) + y - 3y = 0 - 2, that is
- 2x + 7x - 2y = - 2
5x - 2y = - 2
They should leave $3.51 for a tip. So half of $23.40 is $11.70, half of $11.70 is $5.85, and then a fifth of $5.85 is $1.17, then multiply $1.17 by 3.
