I don't get this at all​

Answer:

-5=n

Step-by-step explanation:

75=3(-6n-5)

Distribute the 3

75=-18n-15

Add 15 to both sides

90=-18n

Divide both sides by -18 to get n alone

-5=n

What is a rational number between 7.7 and 7.9
Luda [366]
Hey mate ,

here is your answer

**********************

The average between any two rational numbers is also rational.
(7.7 + 7.9)/2 = 7.8
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal.

Find A={a,b,c} then find A*A.​
Alenkasestr [34]

Assuming you want to do a cartesian product, then you basically form items (x,y)  such that x is in set A, and y is in set A

More generally, A * B will consist of items of the form (x,y) such that x is in A and y is in B. However, we have B = A.

So,

A * A = {

(a,a), (a,b), (a,c)

(b,a), (b,b), (b,c)

(c,a), (c,b), (c,c)

}

I broke things up into separate rows to show that we can form a 3x3 table. Each row is a different x value from the set {a,b,c}. Each column is a different y value from the set {a,b,c}

In my opinion, this helps organize things much better than rather have it all on one single line like this

A * A = { (a,a), (a,b), (a,c), (b,a), (b,b), (b,c), (c,a), (c,b), (c,c) }

which in all honesty looks like a bit of a cluttered mess.
