Answer:

  • C. 4 miles

Step-by-step explanation:

Let the distance between police station and the fire station be x.

According to question we have:

  • the distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station,
  • the distance between the library and the police station is 5 miles.

It can be expressed as:

  • 5 = 2x - 3

Solve the equation for x:

  • 2x = 5 + 3
  • 2x = 8
  • x = 4

<u>Correct choice</u> is C

Given ; 2(10-13x)+9x=-34x+60
rewona [7]

Try comparing your solution with the following:

Solution:

2(10-13x)+9x=-34x+60\\(20-26x)+9x=-34x+60\\20-26x+9x=-34x+60\\20-17x=-34x+60\\20-60=-34x+17x\\-40=-17x\\x=\frac{40}{17}

Answer:

x=\frac{40}{17}

Check:

2[10-13(\frac{40}{17})]+9(\frac{40}{17})=-34(\frac{40}{17})+60\\-20=-20
