Answer: 80
Step-by-step explanation:
Number of visitors in first week = 5
Number of visitors in second week = 10
Number of visitors in third week = 20
The common ratio here is = 10/5 = 2
The fifth term will be:
= ar^n-1
where,
a = first term = 2
r = ratio = 2
n = number of terms = 5
= 5 × 2^(5-1)
= 5 × 2^4
= 5 × 16
= 80

Hope this helps!!
Step-by-step explanation:
1200 x .25 = 300/ 1200 -300 = 900
900 x .25 = 225/ 900 - 225= 675
675 x .25 = 168.75/ 675 - 168.75= 431.25
431.25 x .25 = 107.8125/ 431.25 - 107.8125 = 323.4375
323.4375 x .25 = 80.859 / 323.4375 - 80.859 =242.758

Vertical angles are equal
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60
3x = 57
x = 19
Answer
x = 19
A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
