Answer: by doing the input and the output usually that means add a number or any other mathematical equations.
Step-by-step explanation:
Should be a) difference of squares since 25 and 9 are both perfect squares. A radical will simply that into (5-3) squared, which equals 16.
We have been given a system of equations
and
. We are asked to find the solution of our given system of equations.
To solve our system of equations, we will equate both equations as:









Upon substituting
in equation
, we will get:



Therefore, the solution of our given system of equations would be
and option A is the correct choice.
V = lwh
6 is the length, 3 is the width, and 4 is the height.
V = 6 x 3 x 4
V = 72
Answer:
The price of collection of novels before taxes was <u>$409.10</u>.
Step-by-step explanation:
Given:
Ava bought a collection of hardcover novels and paid $450 including sales tax.
The sales tax is 10%.
Now, to find the price of collection of novels before taxes.
Let the price of collection of novels before sales tax be
.
The price of collection of novels including sales tax = $450.
Rate of sales tax = 10%.
Now, to get the price before sales tax by putting an equation:




<em>Adding both sides by 0.10</em>
<em> we get:</em>
<em />
<em />
<em>Dividing both sides by 1.10 we get:</em>

Therefore, the price of collection of novels before taxes was $409.10.
