So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:
Next, add the two equations together to get 
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, the solution is (2,-5), or A.</u>
First you need to solve for how much you lose for each individual tax, so 420x.0765 will give you how much money you lose to social security tax, then do the same for the other types and add them together, the value will give you the amount you have lost, so taking the total (420) minus the amount lost you will have the amount that you can "take home"
So 420-((420x.0765)+(420x.22)+(420x.0595)) = amount still in your pocket
6* 25 = 150 = (6*20= 120) + (6*5=30) Then Add 120+30= 150 so your answer is 5
Answer:
C. 3.33 hours
Step-by-step explanation:
Use the algebra work equation:
= 
+ 
, where tb is the time to work together, t1 is the time it takes one person, and t2 is the time it takes the other person
Plug in the values we know:
= 
+ 
= 
+ 
= 
20 = 6tb
3.33 = tb
So, it would take them 3.33 hours when working together.
A.
B.
Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.
The correct solution:
