6. you add. tat
Answer:
c.) hourly rate
Step-by-step explanation:
The value the coefficient represents can often be learned from its units. The term 8t gives a value in currency units, since the expression 8t+20 is an amount that is to be paid. (We can only add like terms, so both 8t and 20 must have currency units.)
The value of t has units of hours, so the coefficient 8 must have units that are ...
8 currency units/hour
That is, multiplying by hours gives currency units.
In this context, a number with units of <em>currency units per hour</em> is most likely the hourly rate of the rental.

Answer:
Step-by-step explanation:
Given

The solution in radical form
Rewrite as:
Using the quadratic formula, we have:
Where
a = 1
b = -10
c = -6
So, we have:
Split the roots
Express as 2
Split the fraction
Let adults = X
Then children would be 2x ( Twice as many as adults, means 2 times the amount of adults)
Now we have adults plus children equal 36:
X + 2X = 36
2X + X = 3x
Now we have 3X = 36
Divide both sides by 3 to solve for X
X = 36/3
X = 12
2X = 2*12 = 24
There were 12 adults and 24 children
