Answer:
{-8, 8}
Step-by-step explanation:
Simplify 7· |n| = 56 by dividing both sides by 7:
|n| = 8
Because this is an absolute value equation, there are two separate solutions. One is n = +8 and the other is n = -8.
Answer:
= 
Step-by-step explanation:
The n th term of a geometric sequence is
= 
Substitute in values
= 320 × 
= 320 × 
= 
= = 0.625
2 x 13
would be the answer since if u divide 26 by 2 you get 13.
The perimeter of the circle is also known as the circumference that said figure out what the diameter is and multiply that by pi (3.14)
Answer:
11/12
Step-by-step explanation:
Nesta questão, estamos interessados em saber em que fração do álbum de figurinhas ambos contribuíram.
Pela pergunta, ficamos sabendo que Karina contribuiu com 1/6 enquanto Cristina contribuiu com 3/4.
Portanto, para encontrar a fração com a qual ambos contribuem, simplesmente adicionamos as duas frações.
Matematicamente, isso seria 1/6 + 3/4 = (2 + 9) / 12 = 11/12
