If you meant:
64.3-3*(2³)/2
That would be 52.3 :)
Im not sure ask ur teacher
Answer:
step 2 to step 3
Step-by-step explanation:
step 2
2x - 7 = 3 ( add 7 to both sides )
2x = 10 ( error was made here in that they had - 4 )
Question 1)
Let "y" denotes the number of yards and "m" denotes the number of meters. According to the give statement, measurement in yards can be changed to measurement in meters by multiplying the measure in yards by 0.9144.
So,
Measure in Meter = 0.9144 x Measure in Yards
m = 0.9144y
Question 2)
We are to convert 7200 yards into meters. Using the values in above equation we can write:
m = 0.9144 x 7200
m = 6583.68 meters
This means 7200 yards are equivalent to 6583.68 meters..
Question 3)
We are to convert 2500 meters to yards.
Using the value in above equation, we get:
2500=0.9144y
⇒
y = 2500/0.9144
y = 2734.03 yards
So this means 2500 meters are equivalent to 2734.03 yards.
The formula that explain the arithmetic sequence is 
Step-by-step explanation:
The formula of the nth term in an arithmetic sequence is
, where
- a is the first term
- d is the common difference between the consecutive terms
∵
,
, 0 ,
are some terms of an arithmetic sequence
∵ The difference between two consecutive terms =
- 
∴ The difference between two consecutive terms =
+
= 
∴ The common difference = 
∴ d = 
∵ The first term is 
∴ a = 
- Substitute a and d in the formula above
∴ 
- Simplify the right hand side
∴ 
- Add like terms
∴
