Answer:
The shoes at the other store could be at the most 70.13.
Step-by-step explanation:
In order to find this, we need to set them equal to each other. Start by multiplying the first cost by the amount of the total price you'll be paying.
65.75 * 80%
And the other side would be the amount of the total price being paid times x.
x * 75%
Now set them equal to each other and solve.
65.75 * 80% = x * 75%
52.60 = x * 75%
70.13 = x
Answer:
5x - 2y = -2
Step-by-step explanation:
When subtracting one equation from the other, we are essentially just subtracting the left side of the second equation from the left side of the first equation and doing the same thing with the two right sides.
Here, we are subtracting (-7x + 3y) from (-2x + y):
(-2x + y) - (-7x + 3y)
Let's get rid of these parentheses. Remember that when we have a subtraction sign before a parentheses, we need to distribute a -1 to each term within those parentheses:
(-2x + y) - (-7x + 3y) = -2x + y + 7x - 3y = -2x + 7x + y - 3y = 5x - 2y
Now on the right side, we're subtracting 2 from 0:
0 - 2 = -2
Put it all together:
5x - 2y = -2
Hope this helps!
