This is problem #9. I'm not sure how to solve #10, although the solution may be found in a similar way.
last bubble one i guess ok
Answer:
x=-8
y=4
Step-by-step explanation:
first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16
3x+2y=-16
(x+9y=28)3 _multiply with 3
3x+2y=-16
3x+27y=84
use minus(-) =3x-3x=0
=2y-27y=-25y
=-16-84=-100
the result:-25y=-100
y=4
take any simple equation and replace y with 4
x+9y=28
x+9(4)=28
x+36=28
x=28-36
x=-8
answer:x=-8,y=4
We know that Billy caught total 4+10=14 fishes including trout and catfish.
P(catching the catfish):
10/14
Simplify that into 5/7. As a result, the probability that the next fish that Billy catches will be a catfish is 5/7. Hope it help!
Because you are 12 you put down
12
x can be anything so if you write
12x
You can later substitute it for 3. 12(3)
Your uncle is 2 years more
12x+2 is your equation
or
12(3) + 2
