Answer:
Step-by-step explanation:
-15/10 - 8/10= - 23/10 Since both are a negative, you add the top or the numerator.
Answer:
-2/3, -0.6, 0.2, 1/2, 5/8
Step-by-step explanation:
What you do is you have to make them into decimals.
-0.6 and 0.2 are already in decimals.
-2/3 as a decimal is -0.667
1/2 as a decimal is 0.5
5/8 as a decimal is 0.625
-2/3, -0.6, 0.2, 1/2, 5/8 is your answer.
ans is b...multiply eqn 1 by -2 and eqn 2 by 3
=》 -6x + 10y = 4...eqn 3
=》 6x + 3y = 9...eqn 4
add eqn 3 and 4...
=》13y = 13
=》y =1 and x = 1
A pythagorean theorem must satisfy a² + b² = c²
16² + 20² = 25²
256 + 400 = 625
656 ≠ 625 so no, the set 16, 20, 25 does not represent a pythagorean triple
