Answer:
$191.25
Step-by-step explanation:
To find the price after the discount you will need to turn the percentage into a decimal. Since 1 represent as a 100% we will subtract 15% percent from it. To do this we will divide 15 by 100 to get .15. Subtract .15 from 1. This will give you .85. With .85 you multiply it by the original price of the shoes ($225). This will give you 191.25.
A square has exactly one pair of parallel sides
Answer:
-2,2
Step-by-step explanation:
We can solve this using substitution.
because x-y=2.5
x=y+2.5
Now substitute x into other equation.
2(y+2.5)^2-2y=125
2y^2+10y+12.5-2y=125
2y^2+8y-112.5=0
Now comes the ugly part
y=-4+-sqrt(16+900)
y=-4+-sqrt916
y=-4+-2sqrt229
x=-1.5+-2sqrt229
Answer:
The answer is 1600.
Step-by-step explanation:
Just multiply 400 by 4.
