Given
Required
Her salary in that month
Given that she spent 
of her salary on shopping, this implies that she has 
of her salary left
From what's left, she gave her sister 
This means she gave her sister 
Sister = 
Calculating a fraction of what's left
Recall that she has Rs11,040
This means that
Multiply both sides by 
Hence, her salary for that month was Rs23000
Answer:
(4,-1)
Step-by-step explanation:
You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11
+ 7x+3y=25
--------------
After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)
Answer:
choice B
Step-by-step explanation:
You should first draw a strait line across your paper. Draw the 55 degree angle with your protractor. Then draw the 125 degree angle it should stop at where the line of the 55 degree angle you just drew. These two angles add up to 180 degrees. 125+55 = 180. These are known as supplementary angles.
Formula for a square is s^2.
(8x-1)^2=
(8x-1)(8x-1)=
64x-8x-8x+1=
64x-16x+1=
48x+1
Therefore, the area of the square mentioned in the question is 48x+1.
