Answer:
The cost is the same at 10 videos.
Your equations are:
4x
2x + 20
The answer, 10, means that there are 10 videos.
Step-by-step explanation:
First, write out your two equations. It should look like this:
Dreama's Videos: 4x
Membership: 2x + 20
To solve, I keep filling in numbers for x until you get the answer. If you fill in the number 10, for x, you get that it costs $40 for both of them. So, the cost is the same at 10 videos. Your two equations are 4x and 2x + 20. The x represents the number of videos. So, when you get the number 10, it means that there are 10 videos. Hope this helped!
This is part of the Fibonacci sequence. The next number is 21. Look at how much each number increases and the number before it.
1+1=2 (the number after 1 and 1)
1+2=3 (the number after 1 and 2)
2+3=5 (the number after 2 and 3)
So to solve we add 13+8=21
Answer: 
Step-by-step explanation:
Given : Number of good laptops =20
Number of defective ones=3
Total laptops =23
If 2 laptops were selected, then the probability that none of them was defective would be = 
The probability that at least one will be defective= 1- P(none of them is defective)
Hence, the probability that at least one will be defective. 
Answer:
w = 9 ft
l = 13 ft
Step-by-step explanation:
2w + 2(w+4) = 44
simplify:
4w + 8 = 44
4w = 36
w = 9 ft
l = 13 ft
