What is the gcf of negative 9 and 15?
The GCF is 3.
How do you figure out what ten minus negative fifteen is?
10--15 = 10+15 = 25 Two negative signs cancel out to be a positive therefore you add them together
What is the product of 9 and 15?
TOP TIP!!!: If you have a multiplication that contains an even number of negatives, IGNORE THE MINUS SIGNS! -9 x -15 is exactly the same as 9 x 15 ie 135.
What is the least common denominator of -15 and 10?
If those are the denominators, then the the negative part of -15 should be transferred to the numerator, eg if the fraction is 4/(-15) then make it (-4)/15, or if it is (-4)/(-15) make it (--4)/15 = 4/15. Then the lcm of 15 and 10 is 30. (Otherwise you are likely to have trouble in getting your signs right if you use a negative denominator.)
What is 3Z equals 9 equals 15?
It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
