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

lana [24]
22     = 100%
26,40 = x%

26,4*100/22=120%
x=120%

120%-100%=20%
The answer is 20%

Question 6
Aleksandr-060686 [28]

Answer:

33 children

62 adults

Step-by-step explanation:

Set up 2 equations (a=adults c=children)

The first equation will be 3.25(a)+3 = 300.5

The second equation will be a + c = 95

Subtract c from both sides to get:

a = 95 - c

Replace c in the 1st equation to get:

3.25(95-c) + 3c = 300.5

Distribute 3.25 to 95 and -c:

308.75 - 3.25c + 3c = 300.5

Subtract 308.75 from both sides:

-3.25c + 3c = 300.5 - 308.75

Combine like terms:

-0.25c = -8.25

Divide by -0.25

children = 33

Subtract 33 from 95 to get

adults = 62
