55% were in the rest of the train. it says "d" though, so I can't tell you the exact number.
Answer:
x=13
y= -9
(13, -9)
Step-by-step explanation:
If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.
Then, we can take that equation and plug it into the bottom one so
3x+4(4-x)=3
Simplify:
3x+16-4x=3
-x=-13
x=13
We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)
So, 13+y=4 which y= -9
The answer is A
Hopefully it will be correct
we name bases k , k+6. so
area: 96= (k + k+6).8/2
=> 2k+6= 24 => k=9
