Answer:
a₁ = 6
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a₁ is the first term and r the common ratio
Here 
= 1530 and r = 2, thus
= 1530 , that is
a₁ (256 - 1) = 1530
255a₁ = 1530 ( divide both sides by 255 )
a₁ = 6
They are equal
(-16)-(-4)
*negative and negative make a positive
-16+4= -12
-16+4=-12
They both make -12. They both are equal
Metric: kilometers
Imperial: Miles
Answer:
Step-by-step explanation:
Your gonna subtract the cost of the pair earrings from the total. 260-15=245, then you will divide 245 by 7. 245/7=35. So each bracelet cost's 35 each.
So basically what you wanna do is multiply across giving you 40/88 which you can simplify down to 5/11
Hope this helps :D
