Answer:
1, -4.5
Step-by-step explanation:
What do you mean by estimating the solution?
y=-6x+4
x-4(-6x+4)=19
x+24x-16=19
25x=25
x=1
1-4y=19
-4y=18
y=-4.5
Answer: 17.14 ft
<u>Step-by-step explanation:</u>
The area of the flower bed is 60 ft x 80 ft = 4800 ft²
The perimeter of the sidewalk that surrounds the flower bed is:
- 2(60 ft) + 2(80 ft)
- = 120 ft + 160 ft
- = 280 ft
The area of the sidewalk is:
area of sidewalk = area of flower bed
280w = 4800


≈ 17.14
