Step-by-step explanation:
A negative number divided by a positive number is always negative.
819/9=91
-819/9=<u>-91</u>
The first step to find the gcf of 12 and 90 is to list the factors of each number. The factors of 12 are 1, 2, 3, 4, 6 and 12. The factors of 90 are 1, 2, 3, 5, 6<span>, 9, 10, 15, 18, 30, 45 and 90. So the greatest common factor is 90 Buddy.</span>
First set up two equations: 4c+5p=65. C+p=14. Solve one equation and sub it in for the other: C=14-p: 4(14-p)+5p=65, 56-4p+5p=65, p=9. Sub in what you now know: c+9=14, c=5. Check both equations to make sure it's right and you get: Pepperoni=9 cheese=5 :) hope this helps!
