Becky was trying to open the door, but it was stuck,
so she asked me to compound on it with her.
First you need to make a multiplier:
1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
Answer:
guess and check
Step-by-step explanation:
Linear equation systems usually have two or more variables to find.
The values for these variables can be found by different methods, some of them are indeed graphing, substitution and with matrices.
So these are correct options that are used to solve linear systems of equations.
On the other hand, the guess and check method is not used to find the solution of these systems, since the more variables the system has the more difficult it is to guess the answer,<u> the graphic and mathematical methods are more effective and reliable.</u>
Answer:
Step-by-step explanation:
time after 40 meters to 80 meters=12-7=5 s
distance=80-40=40 m
max. speed=40/5=8 m/s
(4,1) because it is the ordered pair that passes through the line
