Answer:
x = 5.2
Step-by-step explanation:
x/(13-x) = 2/3
3x = 2(13 - x)
3x = 26 - 2x
3x + 2x = 26
5x = 26
x = 26/5
x = 5.2
12.1 per second or 12.1 • 60 seconds or a minute is 726
5 1 and 8 only one side is negative
Answer:
8 apples
Step-by-step explanation:
There are 3 apples with a mass of 39 grams, 2 apples with a mass of 40 grams, 1 apple with a mass of 41 grams, and 1 apple with a mass of 43, and lastly one apple with a mas of 44 grams.
There are three types of progression: arithmetic progression, geometric progression and harmonic progression. Arithmetic progression is a sequence of numbers or variables that has a common difference. Geometric progression has a common ratio, while harmonic progression is just the reciprocal of the sequence in arithmetic progression.
Example of an arithmetic sequence is: 34, 37, 40, 43, 46. The adjacent terms have a common difference of 3. Mathematicians have already derived equations for arithmetic progression so it would be just convenient for us to predict the next numbers or missing numbers in the sequence. These equations are:
An = A1 + (n-1)d
Sn = (n/2)(A1 + An)
where
An is the nth term in the sequence
A1 is the first term in the sequence
n is the total number of terms int he sequence
d is the common difference
Sn is the sum of all the terms in the sequence
These two equations describe an arithmetic sequence.
