a motel clerk counts his $1 and $10 bills at the end of the day. he finds that he has a total of 56 bills having a combined mone
alina1380 [7]
We can write a system of equations:

1x + 10y = 182
x + y = 56

Where 'x' is the number of $1 bills, and 'y' is the number of $10 bills.

To find this we can solve using substitution.

Re-arrange the 2nd equation:

x + y = 56

Subtract 'y' to both sides:

x = -y + 56

Now we can plug in '-y + 56' for 'x' in the first equation.

1x + 10y = 182

1(-y + 56) + 10y = 182

-y + 56 + 10y = 182

Subtract 56 to both sides:

-y + 10y = 126

Combine like terms:

9y = 126

Divide 9 to both sides:

y = 14

Now we can plug this into any of the two equations to find the 'x' value.

x + y = 56

x + 14 = 56

Subtract 14 to both sides:

x = 42

So our final answer is (42, 14).

This means that the motel clerk had 42 $1 bills, and 14 $10 bills.

Name the property of real numbers illustrated by the equation 16(3t + 4v) = 48t + 64v.
scZoUnD [109]
The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.

 Therefore, the answer is: Distributive property.

 As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:

 16(3t+4v)
 (16)(3t)+(16)(4v)
 48t+64v

The quantity p varies inversely as the square of (q + 2) <br>p=5 when q = 3 <br>Find p when q = 8​
MArishka [77]

Answer:

p = 1.25

Step-by-step explanation:

varies inversely

p (q + 2)² = k

-----------------------

Find k

p=5 when q = 3

5(3 + 2)² = k

5(25) = k

125 = k

----------------------

Find p when q = 8​

p(8 + 2)² = 125

p(100) = 125

divide both sides by 100

p = 1.25
