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

3x − x − 1 = 15<br> What is x
azamat

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8

Describe how to round 678 to the nearest hundred.
Vika [28.1K]
The nearest hundred will be in the hundredth place

For example, 2000

2 is in the thousands, followed by hundreds, ten, ones

to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.

So in this case 678 will equal 700

Example: if it were 644, then it would be 600

hope this helps

BRAINLIEST AND 50 PTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
frozen [14]

Answer:

The answer is A. Because 11/9 is greater than 1, the product of 4/5 and ​11/9 ​is greater than ​4/5

9/9 is exactly 1. 11/9 is greater than 9/9, so 11/9 is greater than 1. If I added 4/5, the answer is larger than 11/9, therefore the answer is A.
