Answer:

The term to add is

$-\frac{1}{3} x$

Step-by-step explanation:

Let

b ----> the term to add

we have

$\frac{5}{6}x-4+b=\frac{1}{2} x-4$

Solve for b

Adds 4 both sides

$\frac{5}{6}x+b=\frac{1}{2} x$

subtract 5/6x both sides

$b=\frac{1}{2} x-\frac{5}{6}x$

Remember that

$\frac{1}{2}=\frac{3}{6}$

substitute

$b=\frac{3}{6} x-\frac{5}{6}x$

$b=-\frac{2}{6} x$

Simplify

$b=-\frac{1}{3} x$

therefore

The term to add is

$-\frac{1}{3} x$

Which number is the solution of n/3= -12? A: -36 B: -4 C: 4 D: 36

faust18 [17]

N/3= -12.
You want to get "N" by itself. On one side of the equation, with no other number. To do this, we do the opposite of what we have next to the letter "N"
In this case, N is being divided by 3, and the opposite of dividing is multiplying.
So you need to multiply both sides by 3.
The 3's on the left side cancel out, leaving N by itself.
Now you have N= -12 * 3
-12 * 3 = -36

So N = -36

Round $6.4442 to the nearest cent.

Answer:

6.40

Step-by-step explanation:

Find the number in the tenth place (the first 4) and look one place to the right for the rounding digit (the second 4).

Round up if this number is greater than or equal to 5

and round down if it is less than 5.

4 is less than five, therefore should be rounded down.
