Answer:
$244.25
Step-by-step explanation:
First, the question is asking what the change in her savings account balance is each month. So, you know that you are looking for the amount that is lost each month. When it says that at the end of the year, she has payed $2,931 , what is implied is that she has spent that much over 12 months. So all that is needed to do is divide her balance change over the year by 12 to find the monthly balance change.
we know that
If a ordered pair (x,y) is a solution of the equation, then the ordered pair must satisfy the equation
we have the equation

Let's verify all the cases to determine the solution to the problem.
<u>case A)</u> point 
Substitute the values of x and y in the equation



-------> is true
therefore
The point
is a solution of the equation
<u>case B)</u> point 
Substitute the values of x and y in the equation



-------> is true
therefore
The point
is a solution of the equation
<u>case C)</u> point 
Substitute the values of x and y in the equation



-------> is not true
therefore
The point
is not a solution of the equation
<u>case D)</u> point 
Substitute the values of x and y in the equation



-------> is not true
therefore
The point
is not a solution of the equation
therefore
<u>the answer is </u>

Answer:
The answer is A. Angles are proportional, side lengths are larger.
Step-by-step explanation:
That’s because scale factors greater than one make a shape larger, and the angles are proportional it's the lengths of the size that change.
Answer:
2.23kg
Step-by-step explanation:
If you can get 1 kg for $4.50. You can perform a ratio to find out how much you get for $10.
1/4.50=x/10
.2222222=x/10
multiply the 10 on both sides
x=2.23 kg for $10
