Alright, 1, 2, and 4 are correct but 3 is not.
The error you made could be hard to notice but it was made. So let's put the equation up, 6x-(2x-9)=-31. Your error occurred when you didn;t distribute the negative sign for (2x-9), if you woud have distributed it then the equation would then be simplified into 6x-2x+9=31. You then add like terms and get 4x+9=31, subtract 9 on both sides and you'll get 4x=22. Divide 4 on both sides to isolate the variable and you get x=5.5
Answer:
The total money spend on total tax of purchase is $4.625
Step-by-step explanation:
Given as :
The percentage of sales tax applied on gasoline purchase = 8.5%
The percentage of excise tax applied on gasoline purchase = 10%
The price of gasoline before tax = $25
Let The total money on total tax of purchase = $x
Now, Total percentage of tax = sales tax percentage + excise tax percentage
i.e Total percentage of tax = 8.5% + 10%
Or, Total percentage of tax = 18.5%
<u>Again</u>
total money on total tax of purchase = $25 of total total tax percentage
Or, x = $25 × 18.5%
Or, x = $25 × 
Or, x = $25 × 0.185
∴ x = $4.625
So,The total money on total tax of purchase = x = $4.625
Hence,The total money spend on total tax of purchase is $4.625 Answer
Answer:
The price of the burrito is $3.5 and the price of the taco is $2.5.
Step-by-step explanation:
2x+5y=19.5
5x+2y=22.5
------------------
5(2x+5y)=5(19.5)
-2(5x+2y)=-2(22.5)
-----------------------------
10x+25y=97.5
-10x-4y=-45
-----------------------
21y=52.5
y=52.5/21=2.5
2x+5(2.5)=19.5
2x+12.5=19.5
2x=19.5-12.5
2x=7
x=7/2=3.5
x=3.5, y=2.5
The price of the burrito is $3.5 and the price of the taco is $2.5.
3 of anything positive is greater than 2 of the same thing.
I can't think of an exception.
