Answer:
42
Step-by-step explanation:
Find the prime factorization of 126
126 = 2 × 3 × 3 × 7
Find the prime factorization of 420
420 = 2 × 2 × 3 × 5 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3 × 7
GCF = 42
Answer:
Its to multiply the numerators by each other and the denominators by each other
Step-by-step explanation:
If adding and subtracting fractions is about finding the least common denominator
dividing fractions is to keep the first fraction,multiply and reverse the second fraction,so dividing is pretty similar to multiplying but just switching the divide sign with a multiplication sign and reversing the second fraction from numerator/denominator to denominator/numerator
and there is always a big difference if you multiply/divide or add/subtract
I'm thinking this is the anwer if im right
Answer:
Step-by-step explanation:4/8
The answer is k = 15. A straight line is 180 degrees. L to Y is a ray which is a line. And M to X is a straight line. So the interior angle Y is the same as 4k+5 as well as 6k+10.
So your equation would look like this...
180=115+4k+5
180=120+4k
-120 -120
60=4k
60/4= 4k/4
15=k
