19 + 8 = h/3or h/3 = 27Multiply both sides by 3h = 27*3 = 81

19 = (h/3) - 8 

Quick reminder of all the inverse operations!
Normal Operation -> Inverse Operation

Addition -> Subtraction
Subtraction -> Addition

Multiplication -> Division
Division -> Multiplication

With that out of the way, we can move onto the problem at hand! 
19 = (h/3) - 8

When trying to solve for a variable you must first get the variables expression alone (In this case the expression (h/3)). To do that in this case we must get rid of a 8 which is being subtracted from (h/3). So the inverse operation of subtraction is addition, thus we add 8 on both sides! Like a so...: 

19 + 8 = (h/3) - 8 + 8

The two 8s on the right cancel out, because -8 + 8 = 0. 

19 + 8 = (h/3)

Simplify the right side by adding together 19 and 8. 

27 = (h/3)

Now we need to get h alone by removing the 3 which it is being divided by. So we use the inverse operation of division which is multiplication. 

27 * 3 = (h/3) * 3

The 3s on the right cancel out, because 1/3 * 3 = 1. 

27 * 3 = h

81 = h 

So! Our final answer is....
h =  81

What is -5/12 - 4/14 + 6/34
andrew11 [14]

Answer:

4 1/2

Step-by-step explanation:

Look at this expression as given in the original problem; the numbers, properly typewritten, are    -5  1/2,  - 4  1/4,  + 6  3/4.

We want to combine these three numbers into one.

To do this, we need the LCD; it is 4.

Thus, -5  1/2 is rewritten as  -5  2/4.

Then we have

-5  2/4 - 4  1/4 + 6  3/4  = -5 -4 + 6 + 2/4 + 1/4 + 3/4.

This simplifies to:                 +3 + 6/4, or 3 + 1  + 2/4, or

                                                                      4  1/2

What happens to the value of the expression 1+3f1+3f1, plus, 3, f as fff increases? Choose 1 answer: Choose 1 answer: (Choice A)
Leto [7]

Answer:

A. It Increases

Step-by-step explanation:

Given the expression:

1+3f

When f=1, 1+3f=1+3(1)=1+3=4

When f=2, 1+3f=1+3(2)=1+6=7

When f=3, 1+3f=1+3(3)=1+9=10

We can see that the value of the given expression for each successive term increases and in fact form the sequence

4,7,10,...

Therefore, when f increases, 1+3f increases.
