lions [1.4K]

Answer:

12.5%

Step-by-step explanation:

The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??

The increase is 900 - 800 = 100

To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:

$\frac{100}{800}*100=12.5$

So the increase is 12.5% and thus the general sales tax is 12.5%

Solve the system.<br> 2x+y = 3<br> -2y = 14 - 6x

bezimeni [28]

Answer:

The solution is: (2, -1)

Step-by-step explanation:

First we rewrite the second system equation

$-2y = 14 - 6x$ → $6x-2y=14$

Now we have the following system of equations:

$2x+y = 3$

$6x-2y=14$

To solve the system multiply the first equation by -3 and add it to the second equation

$-6x+-3y = -9$

$6x-2y=14$

--------------------------------------

$0-5y=5$

$y=-1$

Now we substitute the value of y in the first equation and solve for x

$2x-1 = 3$

$2x= 4$

$x= 2$

The solution is: (2, -1)
