Answer:
The total price that he has to pay is $21.8.
Step-by-step explanation:
Mr. O'Donnell goes to the store to buy a shirt. The shirt is $20, but he also has to pay a 9% tax.
First you convert the sales tax percentage to its decimal form: in this case 9% becomes 0.09.
To calculate the cost of the tax, the following multiplication must be performed:
cost of product or service* sales tax (in decimal form) = total sales tax
In this case:
$20*0.09= $1.8
Finally, you must add the value of the total sales tax to the cost of the product or service to obtain the total cost. In this case:
$20 + $1.8= $21.8
So, <u><em>the total price that he has to pay is $21.8.</em></u>
The solution to the system of equation is (3/2, -1/2)
<h3>System of equations</h3>
Given the following system of equations as shown;
(3x+y=4 .... * 4
2x-4y=5 ..... * 1
_______________
12x+4y=16
2x-4y=5
Add both equations
12x+2x = 16 + 5
14x = 21
x = 3/2
Substitute x = 3/2 into any of the equation to have;
2x-4y=5
2(3/2) - 4y = 5
3 - 4y = 5
-4y = 5 - 3
-4y = 2
y = -1/2
Hence the solution to the system of equation is (3/2, -1/2)

Answer:
that would be 0 lines for symmetry
PQ and RQ are Congruent, therefore, SQ bisects PR. SR=PS, SR=17 so PS=17
B=17
