Answer:
A
Step-by-step explanation:
C and A ...................
Let (a) be the first cat
let (b) be the second cat
a +b=11kg-----(1)
a=b+1500g⇒(1.5 kg)-------(2)
so now u have a system of two unknowns
a=11-b
substitute a in (2)
11-b=b+1.5
11-1.5=2b
2b=9.5
b=9.5/2=4.75
subs. b in (1)
a+b=11
a+4.75=11
a=11-4.75=6.25
so cat (a) is 6.25 kg
and (b) is 4.75 kg
hope I helped
Answer:
Step-by-step explanation:
Answer:(A)= (-x^11)/(y^7)
(B)= (1/12xy^5)
Step-by-step explanation:
(A) (3x^3y^-2)(-2x^-3y^2)^-5/(6x^7y^-5)
[(3x^3y^-2)(-2x^15y^-10)]/(6x^7y^-5)
(6x^18y^5)/(-6x^7y^12)
(-6x^11)/(6y^7)
(-x^11)/(y^7)
(B) [(12x^-3y^5)/(x^-4)]^-1
(1/12xy^5)
Terms: 2, 8, 15. variables: x, y. coefficient:2,8
let me know if it’s correct!
