Help please I really need it
KatRina [158]

First write the equation 8 + 12 > x because according to the triangle property, the sum of any 2 sides have to be greater than the third side. This means that the difference of any two sides should be smaller than the third side.

Komok [63]

Answer: Amber use 30 feet of basic tiles and 6 feet of decorative tiles.


Step-by-step explanation:

Let x be the foot  of basic tiles and y be the foot of decorative tiles.

Now, according to the question, we have the following equations

x+y=36\\y=36-x\ .......(1)\\\\8x+20y=36\times10\\2x+5y=90.......(2)\ \ \ [\text{divide equation by 4}]

Put y=36-x in (2), we get

2x+5(36-x)=90\\\Rightarrow2x+180-5x=90\\\Rightarrow-3x=-90\\\Rightarrow\ x=30\\\\\Rightarrow\ y=36-30=6

Hence, Amber use 30 feet of basic tiles and 6 feet of decorative tiles.
