30 = 4x + 10
20 = 4x
x = 5
answer
x = 5 It's B. second choice
Answer:
ofc! :D
Step-by-step explanation:
i- x represents the input
ii- y represents the output
iii- yes, the input (x) is 4 times greater than the output (y)
b just plot them like normal on a coordinate grid :D
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.
Answer:
4x + 4y + 12
Step-by-step explanation:
x + 3y − y + 3x + 2(2 + 4 + y)
Apply Distributive Property:
2(2 + 4 + y)
2*2=4
2*4=8
2*y = 2y
x + 3y − y + 3x + 4 + 8 + 2y
Combine Like Terms:
x + 3x +2y +3y - y + 4 + 8
4x + 4y + 12
Answer:
70
