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:

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

nignag [31]

Answer:

parallel

Step-by-step explanation:

Solve both equations for y to make it easier to compare them.

2x - 5y = 0 ↔ 5y = 2x, or y = (5/2)x.

y = (5/2)x - 3

Since the slopes are the same, the two lines are parallel.

Sarah received $55 for her birthday. She used some of that money to buy 3 shirts priced at m dollars each.

jolli1 [7]

Answer:

$55 - 3m$

Step-by-step explanation:

Sarah has $55

Her expenses are 3 shirts priced at $m each.

Total cost of 3 shirts at $m each would be the multiplication of each:

3 * m = 3m

The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:

Remaining Money = 55 - 3m
