Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:
So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
For this divide 365 by 5 and the number you get is your answer.
so,
365/5 = 73
So, the answer is 73 times
.............................................................
4.7 -7.25x+ 8.623x -3.8
= (4.7 -3.8)+ (8.623x -7.25x) (combine like terms)
= 0.9+ 1.373x
The final answer is 1.373x+ 0.9~
Answer:
%18 tip
Step-by-step explanation:
The dinner cost was $29 before tip
after tip it was $32.22
34.22-29= $5.22 she tipped
$29 * %x = $5.22
After solving this equation, the x is %18
You basically have to take it to the power of half.
example to find the square root of 4,
take 4^0.5 = 2
hope this helped
