a train traveled 300 miles in 5 hours. find its rate of speed in miles per hour.

Answers

Answer:

60 miles per hour

Step-by-step explanation:

[tex]Speed = \frac{Distance}{Time}[/tex]

You divide 300 by 5 and you get 60. You always need to divide the upper part to the lower part to reach the distance in ONE UNIT OF TIME. There, you have 5 seconds, yet you need the distance in 1 second.

This all is assuming that the train moved at a constant speed, where

ACCELERATION = 0, which is pretty improbable for a train.

Answer:

x= 4

Step-by-step explanation:

2x + 3( 5x - 7) = 47

2x + 15x - 21 = 47

17x -21 = 47

17x = 47 + 21

17x = 68

x = 68 / 17

x = 4

hope it helps plzz mark me brainliest

Answer:

X = 4 plz brainliest

Step-by-step explanation:

2x+3(5x-7)=47

Distribute

2x + 15x - 21 = 47

Combine like terms

17x -21 = 47

Add 21 to both sides

17x = 68

Divide by 17 both sides

X = 4

Im so confused all i know is that it isn't C

Answers

Well I’m not 100 percent sure but I believe it’s b

Answer:

B.

Step-by-step explanation:

The answer would be B. because 2/3 as a decimal is 0.66666666...... and so on. 2/3 as a percent is 66.66666...... and so on.

2/3 is just 2 divided by 3, that gets you 0.66666..... 2/3 = 0.6666..... (decimal)

Now you know the decimal. The rule to get a percent is to move the decimal point two places to the right to get the percent.
