☆☆☆☆☆3n + 2n = 7 + 4n
5n = 7 + 4n
5n - 4n = 7
n = 7
The additive inverse of 8 is -8. In general, if you have a number, n, the additive inverse is -n because n+(-n)=0. So in this case 8+ (-8)=0.
This is useful in solving equations where we add the additive inverse to both sides of the equation.
m/(-4) = 9
m = 9 x (-4)
m = -36
The numbers are 12, 14 and 16.
Let the numbers by n - 2, n and n + 2, then
(n - 2) + n + (n + 2) = 3n = 42 : n = 14 so n - 2 = 12 and n + 2 = 16.
(3k - 2)(3k - 2) or (3k - 2)2
Yes, negative decimal numbers are rational, as long as it is terminating or repeating.
absolute value of -3 - 6 is 9.

1/1000 equals 0.001
9.67 in fraction form is 967/100 in fraction form
There is no such number. Irrational numbers are infinitely dense. Given any number near 13, there are more irrational numbers between that number and 13 than there are rational numbers in all.
Solving for y:
5y = 9 + 2y
5y - 2y = 9
3y = 9
y = 9/3 = 3

If x=3 and y=-2, 4xy = 4(3)(-2) = 12(-2) = -24
0.727272 is already a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 90909/125000.
It is zero.
It depends:
If the whole number is positive then the result is less than the whole number, eg ½ × 2 = 1 < 2
If the whole number is negative then the result is greater than the whole number, eg ½ × -2 = -1 > -2
"Zero point" is 0. It is an integer, not a fraction.
4 is the only integer between them.
It is 3.8
