Answer:
265
Step-by-step explanation:
All values should add up to 750
85 + 400 + x = 750
485 + x = 750
x = 265
Answer:

Step-by-step explanation:
1) so you want to simplify this monomial first
(divide coefficients by 7)
(3x^6y^5)/2x^2y^9
2) next, you want to eliminate the extra "x" and :y: values
(bring x value with smaller power to the higher power x value)
so
(3x^6*x^-2y^5)/2y^9
(3x^4y^5)/2y^9
(do same thing for "y")
(2x^4)/2y^4
hope this helps
