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.

Please help, 9th grade math

mash [69]

Step-by-step explanation:

y = mx + b, where m is the line's slope and b is the y-intercept.

We have m = -1. When x = -1, y = 2/3.

=> (2/3) = (-1)(-1) + b, b = 2/3 - 1 = -1/3.

Hence the value of b is -1/3.
