Let's find x. This will allow us to find the value of the second expression.
x - 3 = 1
x = 4
Now, we can simply plug this x-value into the second expression to obtain 4^2 - 3(4) - 1 = 3.
Thus, our answer is 3.
The teacher bought 195 tickets because i just did 5460 divided by 28
The correct answer: 7.428 inches
Explanation:
Given the equation is D(r) = 0.145r^2
Where D is the depth and r is the radius
Putting D = 8 inches in the equation
8 = 55.2
r^2= 8/ 0.145
r^2 = 55.2
R^2= 7.428 inches
The radius of depth is 7.428 inche

Answer:
For 2 hours of dog stinting the total cost will be the same for the two services.
Step-by-step explanation:
x to represent the number of hours of dog sitting
<u>Derrick's Dog Sitting </u>
Fixed charged rates = $12
Sitting charges per hour = $7
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $7) = 7x
⇒Total charges of Derrick's Dog Sitting for x hours = Fixed charge + Hourly Rate
= $7x + 12
<u> Darlene's Dog Sitting</u>
Fixed charged rates = $16
Sitting charges per hour = $5
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $5) = 5x
⇒Total charges of Darlene's Dog Sitting<u> </u>for x hours = Fixed charge + Hourly Rate
= $5x + 16
Now, according to the question:
for x hours sitting, both company charges are same.
⇒ $7x + 12 = $5x + 16
or, 7x - 5x = 16 - 12
or, 2x = 4
⇒ x = 2
Hence, for 2 hours of dog stinting the total cost will be the same for the two services.
