Charlotte drives 64 mph for the first 3 hours of her trip and 92 mph for last 4 hours.
german

Answer:

80 mph

Step-by-step explanation:

\boxed{\sf Distance=Speed \times Time}

<u>First leg of trip</u>

  • Speed = 64 mph
  • Time = 3 hours

\implies \sf Distance =64\times 3 = 192\:miles

<u>Second leg of trip</u>

  • Speed = 92 mph
  • Time = 4 hours

\implies \sf Distance=92 \times 4 = 368\:miles

\boxed{\sf Speed=\dfrac{Distance}{Time}}

To find the average speed:

\begin{aligned}\implies \sf Average\:speed & = \sf \dfrac{Total\:distance}{Total\:time}\\\\ & = \sf \dfrac{192+368}{3+4}\\\\& = \sf \dfrac{560}{7}\\\\ & = \sf 80\:mph\end{aligned}

9x-7=-7 how do you solve this problem
borishaifa [10]
<span>9x-7=-7 
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.
