Question

  1. find the length of $overline{uw}$ if $w$ is between $u$ and $v$, $uv = 16.8$ centimeters, and $vw = 7.9$ centimeters.
  2. find the value of $x$ if $rs = 24$ centimeters.
  3. find the length of $overline{lo}$ if $m$ is between $l$ and $o$, $lm = 7x - 9$, $mo = 14$ inches, and $lo = 10x - 7$.
  4. find the value of $x$ if $overline{pq}congoverline{rs}$, $pq = 9x - 7$, and $rs = 29$.
  5. find the measure of $overline{nl}$.
  6. precision if point $p$ is between $a$ and $m$, write a true statement.
  7. hiking a hiking trail is 20 kilometers long. park organizers want to build 5 rest stops for hikers with one on each end of the trail and the other 3 spaced evenly between. how much distance will separate successive rest stops?
  8. race the map shows the route of a race. you are at $y$, 6000 feet from the first checkpoint $a$. the second checkpoint $b$ is located at the mid - point between $a$ and the end of the race $z$. the total race is 3.1 miles. how far apart are the two checkpoints?
  9. field trip the marching band at jefferson high school is taking a field trip from lansing, michigan, to detroit, michigan. the bus driver was told to stop 53 miles into the trip. if the rest of the trip is 41 miles and the entire journey can be represented by the expression $3x + 16$, find the value of $x$.

Explanation:

Response
34.

Step1: Use segment - addition postulate

Since \(UW + VW=UV\), then \(UW = UV - VW\).

Step2: Substitute given values

Given \(UV = 16.8\) cm and \(VW = 7.9\) cm, so \(UW=16.8 - 7.9\).

Step3: Calculate the result

\(UW = 8.9\) cm.

Step1: Use segment - addition postulate

Since \(RS=RT + TS\), and \(RS = 24\) cm, \(RT = 6x - 4\), \(TS = 10\) cm, we have the equation \(6x-4 + 10=24\).

Step2: Simplify the left - hand side

\(6x+6 = 24\).

Step3: Isolate the variable term

Subtract 6 from both sides: \(6x=24 - 6=18\).

Step4: Solve for \(x\)

Divide both sides by 6: \(x=\frac{18}{6}=3\).

Step1: Use segment - addition postulate

Since \(LO=LM + MO\), and \(LO = 10x - 7\), \(LM = 7x - 9\), \(MO = 14\) inches, we get the equation \(10x-7=(7x - 9)+14\).

Step2: Simplify the right - hand side

\(10x-7=7x + 5\).

Step3: Isolate the variable terms

Subtract \(7x\) from both sides: \(10x-7x-7=7x-7x + 5\), \(3x-7 = 5\).

Step4: Isolate the variable

Add 7 to both sides: \(3x=5 + 7 = 12\).

Step5: Solve for \(x\)

Divide both sides by 3: \(x = 4\).

Step6: Find the length of \(LO\)

Substitute \(x = 4\) into \(LO = 10x - 7\), \(LO=10\times4-7=40 - 7 = 33\) inches.

Answer:

\(8.9\) cm
