  1. 15 - 3q + 6 = 9 (re-arrange)
  2. 15 + 6 - 3q = 9 (add)
  3. 21 - 3q = 9 (subtract -21 from both sides)
  4. -3q = 9 - 21 (add)
  5. -3q = -12 (divide both sides by -3)
  6. q = +4

Hope I helped, as an Ambitous rank a brainliest mark would mean the world to me. Now go get that A!

Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?
topjm [15]

\huge \mathcal{ Answer࿐}

  • Error (e) = 50 - 42 = 8 feet

  • assumed value (a) = 42 feet

\boxed{ \mathrm{ \% \: error =  \dfrac{error}{assumed \: value}  \times 100}}

  • \mathrm{ \% \: error  =\dfrac{8}{42}}  \times 100

  • \mathrm{ \% \: error  = \dfrac{800}{42} }

  • \mathrm{ \% \: error  = 19.04 \%}
