Answer: Bottom Right
Step-by-step explanation:
Since the scale factor is 2 all the lengths of the original should be multiplied by that scale factor. Don’t fall for the top left because 2•4 doesn’t equal 6. The top right is just completely off. The bottom left is if the factor is .5
Answer:
B. cost(time)
Step-by-step explanation:
In the information given above, you can eliminate choices "A," and "D," since they're just using the cost of a repair and the time the mechanic works. This leaves us with either "B," or "C." The correct answer is "B," because the cost of the repair depends on whatever is inside the parenthesis (the time).
Answer:
2x-12+5=3x-3
1. subtract 3x-2x
-12+5=x-3
2.-12 add to 5
-7=x-3
3. add three to seven
-4=x
Step-by-step explanation:
Answer:
1 in 15 chance
Step-by-step explanation:
There are 3 character which gives you a 1 in 3 chance of being an elf.
There are 5 defense tools which gives you a 1 in 5 chance of getting magic.
3×5=15 which gives you a 1 in 15 chance of being a magic elf.
You can use prime factorization to find the GCF of a set of numbers. This often works better for large numbers, where generating lists of all factors can be time-consuming.
Here’s how to find the GCF of a set of numbers using prime factorization:
* List the prime factors of each number.
* Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
* Multiply all the circled numbers.
The result is the GCF.
For example, suppose you want to find the GCF of 28, 42, and 70. Step 1 says to list the prime factors of each number. Step 2 says to circle every prime factor that’s common to all three numbers (as shown in the following figure).
As you can see, the numbers 2 and 7 are common factors of all three numbers. Multiply these circled numbers together:
2 · 7 = 14
Thus, the GCF of 28, 42, and 70 is 14.
