11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
System of equations subtraction method
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. ... Substitute the variable back into one of the equations and solve for the other variable. Check the solution--it should satisfy both equations.

Answer:
C
Step-by-step explanation:
In a Pythagorean triple the square on the longest side is equal to the sum of the squares on the other 2 sides.
A
longest side = 10 ⇒ 10² = 100
6² + 8² = 36 + 64 = 100
A is a Pythagorean triple
B
longest side = 17 ⇒ 17² = 289
8² + 15² = 64 + 225 = 289
B is a Pythagorean triple
C
longest side = 9 ⇒ 9² = 81
5² + 8² = 25 + 64 = 89
89 ≠ 81
C is not a Pythagorean triple
D
longest side = 13 ⇒ 13² = 169
5² + 12² = 25 + 144 = 169
D is a Pythagorean triple
Answer:
0
Step-by-step explanation:
12.5/3.79 = 3.2981530343
3.2981530343 rounded = 3.3
1/3 = 3.33333333333333
3.33333333333333 rounded = 3.3
3.3 - 3.3 = 0
