Step-by-step explanation:

1)X represents the time he spent in cardio.

Y represents the time he spent in weighted.

2)If you could put the options on the second one it would be better.

3)4x+y=210

3x+2y=195

y=210-4x

3x+2(210-4x)=195

3x+420-8x=195

5x=420-195

5x=225

x=45

y=30

Total time of one cardi and weighted = 75min= 5/4 h.

4)2x+4y=

90+120=210 total time of week three.

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:

  • perimeter x width
  • = 280w

area of sidewalk = area of flower bed

280w = 4800

\text{w}=\dfrac{4800}{280}

  =\dfrac{120}{7}

  ≈ 17.14
