Answer:
am not sure. the 2 relationships are proportional cus they are even
7x - 9y = 23 x = 11
7*11 - 9y = 23
77 - 9y = 23
-9y = 23 - 77
-9y = - 54
y = -54/-9
y = 6
I hope this explains it.
1037 is the whole number estimate
The three numbers are 1, 3, 9
A geometric progression is a sequence or progression of numbers having a common ratio. It is where the first number is multiplied by the common ratio and the answer would be the second number.Then multiply the second number to the common ratio to create the third number and so on.
While an arithmetic progression is a sequence or progression of numbers having the common difference. It is where the first number is added to the common difference and the answer would become the second number. The second number would be added to the common difference to create a third number and so on.
x1, x2, x3 is a geometric expression1, 3, 9 having the common ratio 3
x1, x2, x3-4 will become an arithmetic progression1, 3, 5 having the common difference 2
From the answer above, subtract 1 from the second and the third term, it will become a geometric expression again.1, 2, 4 having the common ratio 2
Answer:
$194.15
Step-by-step explanation:
First, you need to find what 7% of $1,849 is,
(1,849/100)7=129.43
18 months equals 1.5 years so you then need to multiply the interest for one year by 1.5,
129.43 times 1.5=194.145
But there is no unit of money that goes to 1/1000 of a dollar so you need to round up from $194.145 to $194.15
