The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
Answer:
-48
Step-by-step explanation:
36/-3 = -12
-12 + 2(27/3 * -2)
27/3 = 9
-12 + 2(9 * -2)
9 * -2 = -18
-12 + 2(-18)
2 * -18 = -36
-12 + -36 = -12 - 36
-48
Answer: 1. 12 2. 120
Step-by-step explanation:
1. so basically 9/6=18/x
since they are similir the'd have the same ratio
sooo you just solve for x (multiply 6 by 18, and then divide by 9) and you get 12
2. same thing except you put 6/10=12/x, and solve it (multiply 10 by 12 and divide by 6) and u get 20
dats how i would do it but there are other ways too im sure :)
hope this helps
Answer:
$14.4
Step-by-step explanation:
I don't quite understand this question, but this is what I think
1675/3890 you are dividing 1675 by 3890 so it equals 0.43059...=0.4 simplified to the first decimal
