a resposta será c. Espero que isso ajude você.
Answer:
the answer is D
and here a way to get the correct
and it is to
keep,change the sign,and flip the last fraction
Step-by-step explanation:
6 1/3 + k + 3 5/6 + 5 1/2 = 26 1/6
Add your fractions
6 1/3 + 3 5/6 + 5 1/2 = 15 2/3
now You need to isolate k on one side of the equation by using the subtraction method of equality.
k + 15 2/3 = 26 1/6
k = 10 1/2
Hope this helps

In geometry, there is a theorem that states: The sum of any two sides of a triangle is greater than that of the third
Let's try to plug in and find if any two sides added together will be greater than the third:
a) 2 cm
3+5=8 and 8>2 [acceptable]
2+3=5 but 5=5 [not acceptable]
2+8=10 and 10>5 [acceptable]
b) 3 cm
3+3=6, 6>5 [good]
3+5=8, 8>3 [good]
.....
etc
We found that the answer has to be 2cm, because if we were to add a side of 2cm with 3cm, it would equal to the third side and the theorem states that the sum has to be greater
Hope this helped :) If so, leave a rating :)
