Since this is the formula for the infinite geometric series with
a1 = 42
r = 3/4
Solution will be
sum = 42 / 1-3/4
sum = 42 / 0.25
sum = 168
Therefore, the total is 168
Step-by-step explanation:
Since 1 mi. equals 5,280 feet, you divide 5,280 by 2 to get half of a mile.
5,280 / 2 = 2,640 is half of a mile
Then add to get the answer:
5,280 + 2,640 = 7,920
Therefore, your answer is 7,920, 7,920 is 1.5 miles.

When you multiply 5 by 1 you get 5. When you multiply 5 by 2 you get 10. If you keep doing this, you get a list of multiples of 5.
5
10
15
20
25
30
35
40
45
50
All of these numbers end in either 5 or 0. We can do the same with 2's and 10's.
2
4
6
8
10
12
14
16
18
20
For all 2's we can see that they are all even and end with an even number (0,2,4,6,8)
10
20
30
40
50
60
70
80
90
100
For 10's we can see that they all end in 0.
Answer: -1 and 5.
Step-by-step explanation:
x - 4x = 5 : Move the constant to the left.
x^2 - 4x - 5 = 0 : Rewrite the expression.
x^2 + x - 5x - 5 = 0 : Factor the expressions.
x(x+1) - 5(x+1) = 0 : Factor the expression.
(x+1)(x-5) = 0 : Seperate into possible cases.
x + 1 = 0, x - 5 = 0 : Solve the equations.
x = -1, x = 5 : The equation has 2 solutions.
