Answer:
a= -1
b= -9
c=9
d=3
e=3
f=2
Step-by-step explanation:
Rule of sign:
- (-)×(+)=(-), (-)÷(+)=(-)
- (+)×(-)=(-) , (+)÷(-)=(-)
- (+)×(+)=(+), (+)÷(+)=+
- (-)×(-)=(+), (-)÷(-)=(+)
Given that,
We can rewrite 6-2x as 2x-6, taking (-1) as common factor of (6-2x)
So, a= -1
So, b= -9
The L.C.M of (2x-6) and (2x-6) is (2x-6)
and (2x-6)÷(2x-6)=1
∴c= 9
(3x-9) has a common factor 3 and (2x-6) has a common factor 2.
(3x-9)=3(x-3)
(2x-6)=2(x-3)
∴d=3, e=3 and f=2
Since the denominator and numerator are the product of two polynomial. So, if there is any common element, then can cancel the common factor.
Here the common factor is (x-3). So cancel out (x-3).
The answer to your question is 80
2x-y =3
multiply by 4
8x - 4y = 12
3x +4y = 10 (unchanged equation)
------------------add
11x = 22
answer is A. the first.
first equation multiplied by 4 then sum to get 11x = 22
Answer:There you go X is the middle, a only brother, b only sister.
a X =11
b X =9
a b X =14 (20-6)
a b 2x=20
X=6
So 6 in the middle, 6 on the outside, 5 only brothers, 3 only sisters. let me know if I missed anything but we have a total of 20, 6 with none, 11 with brothers and 9 with sisters
