So we factor out the number and find the number in both numbers so
117=3*3*13
351=3*3*13*3
so the greatest common factor of 117 and 351 is 3*3*13=117
35=7*5
149=prime=149 (prime means no whole factors)
Answer:
x = 12
Step-by-step explanation:
the two equations shown should add up to 180. so I did this equation: (10x-20)+ (6x+8) = 180 and I solved for x
Ok here we go, I will go step-by-step:
So first we have to figure out what y is. we see that the angles outside y are 52 and 59, so we add those together and get 111. now we know whatever y is, it has to equal 180 when added to 111 because it is a straight line. Therefore, angle y is 69 degrees. Now, we also know the angles inside a triangle have to equal 180 when added together. we know two of them. They are 63 and 69. Add those together and we get 132. That means x has to equal 48, to make the inside angles equal 180. The answer is x=48
First, let's convert 0.77 to a fraction.

Multiply by 100

Now make the denominators the same, to make it easier to find which fraction is greater. We can do this by finding the LCM of the denominators, then however many times the denominator goes into that number, we multiply the numerator by the same amount.
For example, the LCM of 100 and 6, is 300. 6 goes into 300 50 times, so the numerator for 4/6 is 200 (4 x 50 = 200). :)

The answer is 0.77 is greater than 4/6. :)
