Answer:
Step-by-step explanation:
- −3 2/3 = x − 1 1/4
- x = - 3 2/3 + 1 1/4
- x = - 2 - 2/3 + 1/4
- x = - 2 - 8/12 + 3/12
- x = - 2 - 5/12
- x = - 2 5/12
Let's just start with x=20 and then do some algebra to it to make it all complicated
x = 20
2 * x = 2 * 20
2x = 40
2x - 13 = 40 - 13
2x - 13 = 27
Answer:
The required formula is:
Step-by-step explanation:
The total number of squares of the the first term = 4
The total number of squares of the the second term = 7
The total number of squares of the the third term = 10
so,



Finding the common difference d


As the common difference 'd' is same, it means the sequence is in arithmetic.
So
If the initial term of an arithmetic progression is
and the common difference of successive members is d, then the nth term of the sequence
is given by:

Therefore, the required formula is:
Answer:

Step-by-step explanation:
Birth Rate in 1994 = 14.6 births per thousand population.
Birth Rate in 2004 = 14.32 births per thousand population.
A linear equation is of the form: y=mx+c
Where:
- x=years after 1994
- y=the birth rate
- m=Yearly Birth Rate
First, we determine the birth rate per year

Therefore, a linear equation that relates y in terms of x is of the form:

When x=0, y=14.6
14.6=-0.028(0)+c
c=14.6
Therefore, the linear equation that relates y in terms of x is:
