Answer:
B: Equation containing fractions
Step-by-step explanation:
A proportion equates two fractions.
A fractional equation contains the unknown in the denominator of one or more terms. (A proportion may be written as a fractional equation.)
Here, the equation has the variable in the numerator of the terms in which it appears, so the equation is not a fractional equation. It is not equating two fractions, so is not a proportion. It contains fractions, so it is an ...

Answer:
The three numbers are 29, 31, and 33.
Step-by-step explanation:
Let's imagine that the three consecutive odd integers are 2x−1, 2x+1, and 2x+3. And we are told the sum is 93 right? So, let's equal the three numbers to 93.
2x − 1 + 2x + 1 + 2x + 3 = 93
6x + 3 = 93
-3 -3
-----------------
6x = 90
/6 /6
----------------
x = 15
Now, plug in x into 2x−1, 2x+1, and 2x+3 to find the three numbers.
2x − 1 2x + 1 2x + 3
2(15) - 1 2(15) + 1 2(15) + 3
30 - 1 30 + 1 30 + 3
= 29 = 31 = 33
Answer:
0.166667
Step-by-step explanation:
1/6 = 0.166667
5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;
