Something times 2 equals 36
now let say that X is the number missing
Replace x by something
x*2-36
2x=36
Divide both sides by 2
x= 18
I hope that's help :)
another way you can do that is to divide 36 by 2 and it will be 18
I hope that's help and if you have questions please ask ;)
42 - 64
Answer:
-22 = -2^1×11^1
Step-by-step explanation:
Factor the following integer:
-22
Hint: | Is 22 divisible by 2?
The last digit of 22 is 2, which means it is even. Therefore 22 is divisible by 2:
22 = 2 11:
-22 = -2×11
Hint: | Now try to factor 11. Is 11 divisible by 2?
11 is not divisible by 2 since 11 is odd and 2 is even:
-22 = -2×11 (11 is not divisible by 2)
Hint: | Is 11 divisible by 3?
The sum of the digits of 11 is 1 + 1 = 2, which is not divisible by 3. This means 11 is not divisible by 3:
-22 = -2×11 (11 is not divisible by 2 or 3)
Hint: | Is 11 divisible by 5?
The last digit of 11 is not 5 or 0, which means 11 is not divisible by 5:
-22 = -2×11 (11 is not divisible by 2, 3 or 5)
Hint: | Is 11 divisible by 7?
Divide 7 into 11:
| | 1 | (quotient)
7 | 1 | 1 |
- | | 7 |
| | 4 | (remainder)
11 is not divisible by 7:
-22 = -2×11 (11 is not divisible by 2, 3, 5 or 7)
Hint: | Is 11 prime?
No primes less than 11 divide into it. Therefore 11 is prime:
-22 = -2×11
Hint: | Express -22 as a product of prime powers.
There is 1 copy of 2 and 1 copy of 11 in the product:
Answer: -22 = -2^1×11^1
To find the ratio of mystery books to the total, divide the number of mystery books by the total number of books and simplify the ratio if possible.
To find the ratio of mystery books to the total, we need to divide the number of mystery books by the total number of books and simplify the ratio if possible.
In this case, the number of mystery books is 12 and the total number of books is 48. So, the ratio of mystery books to the total is 12:48.
We can simplify this ratio by dividing both the numerator and denominator by 12. This gives us a simplified ratio of 1:4.

D.280
Answer:
C. 460
Step-by-step explanation:
We are given a dot graph which shows the number of Hybrid cars sold over the years.
The x-axis represents the years and y-axis represents the number of cars sold.
By looking at the graph, we can infer the following information.
In 2003, the number of cars sold was 120
In 2004, the number of cars sold was 160.
In 2005, the number of cars sold was 260.
In 2006, the number of cars sold was 360.
If you look at the last 3 years, the number of cars sold was increase by 100 by each year.
So, we can predict that in 2007, the number of cars sold was 460.
C. 460
Answer: I predict 460.
