Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =
Common ratio =
The common difference applies to the other given numbers for example :
this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference

Answer:
Alvin: 49
Elga: 40
Step-by-step explanation:
- The equation is 89 = x + (x-9).
- Remove the parenthesis and combine the like terms. 89 = 2x - 9
- Add 9 on both sides. 98 = 2x
- Divide by 2 on both sides. x = 49
- 49 is the age of Alvin. (49-9) 40 is the age of Elga.
First way: x * 1.05
This computes directly what 105% of x will be.
Second way: x + (x * 0.05)
This takes x (which is 100%) and adds 5% of x to it.
Complementary angles add up to 90 degrees.
So we can write:
42 + x = 90
To solve, subtract 42 to both sides:
x = 48
So the complement of a 42 degree angle is a 48 degree angle.
