Step-by-step explanation:

in a geometric series you multiply the n th term by a certain common ratio are in order to get (n+1)th term in arithmetic series you can add the common difference D to the n th term in order to get (n+1) th term.

Combine like terms to create an equivalent expression. 2/5m-4/5-3/5m

Alex17521 [72]

The equivalent expression of $\frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m$ is $\frac{-1}{5}m-\frac{4}{5}$

Step-by-step explanation:

We need to combine like terms to create an equivalent expression. The given expression is: $\frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m$

Like terms:

Like terms are those terms that have the same variables and same exponents.

In the given expression 2/5 m and -3/5 m are like terms.

Combining like terms:

$\frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m$

$=\frac{2}{5}m-\frac{3}{5}m-\frac{4}{5}$

$=\frac{2-3}{5}m-\frac{4}{5}$

$=\frac{-1}{5}m-\frac{4}{5}$

The equivalent expression of $\frac{2}{5}m-\frac{4}{5}-\frac{3}{5}m$ is $\frac{-1}{5}m-\frac{4}{5}$

Two skateboarders, Ron and Bob, are traveling in opposite directions.Ton travels at 8 feet per second and bob travels at 10 feet

omeli [17]

Time taken before they are 2640 feet is 146.67 seconds

<em><u>Solution:</u></em>

The distance is given by formula:

$distance = speed \times time$

<em><u>Ton travels at 8 feet per second</u></em>

Let us assume, time taken = t

speed = 8 feet per second

Then, distance is given as:

Distance covered by Ton = 8t

<em><u>Bob travels at 10 feet per second</u></em>

Then, distance is given as:

Distance covered by Bob = 10t

How long will it take before they are 2640 feet

Which means,

Distance covered by Ton + Distance covered by Bob = 2640

$8t + 10t = 2640\\\\18t = 2640\\\\Divide\ both\ sides\ of\ equation\ by\ 18\\\\t = 146.67$

Thus time taken before they are 2640 feet is 146.67 seconds

<h3><u>Method 2:</u></h3>

Since trains are moving in opposite directions, their speeds must be added

speed = 8 + 10 = 18 feet per second

Given distance = 2640 feet

Therefore, time taken is:

$time = \frac{distance}{speed}\\\\time = \frac{2640}{18} = 146.67 \text{ second }$

Thus time taken before they are 2640 feet is 146.67 seconds
