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

Point C divides segment AB so that AC:AB is 3:8. Which statement is NOT true?<br> HELP!

natima [27]

Given:

It is given that

C divides AB so that, AC:AB = 3:8

To find the wrong option among the given options.

Let us take,

AB = $8x$ unit

AC = $3x$ unit

So,

CB = $8x-3x$

CB = $5x$ unit

So, we can conclude that,

AC: CB: AB = 3:5:8

Hence,

The wrong option is C i.e, Point C is $\frac{3}{5}$ of way from point A to point B.

If you order these 3 from Least I will give 20 points and mark as brilliant 1.)6 3/5, 7 3/4,6.55,6,7.09 2.) 3 8/20,-3.3,3.41,3.2

natulia [17]

Answer:

1.) 6, 6.55, 6 3/5, 7.09, 7 3/4

2.) -3.3, -3 3/12, 3.27, 3 8/20, 3.41

3.) -0.4, 1/25, 4/50, 12/100, 0.8

Explanation:

1.) 6 3/5, 7 3/4, 6.55, 6, 7.09

6 3/5 -> 6.6

7 3/4 -> 7. 75

Therefore: 6, 6.55, 6 3/5, 7.09, 7 3/4

2.) 3 8/20, -3.3, 3.41, 3.27, -3 3/12

3 8/20 -> 3.04

-3 3/12 -> -3.25

Therefore: -3.3, -3 3/12, 3.27, 3 8/20, 3.41

3.) 4/50, 0.8, 12/100, -0.4, 1/25

4/50 -> 0.08

12/100 -> 0.12

1/25 -> 0.04

Therefore: -0.4, 1/25, 4/50, 12/100, 0.8

In 1980 a movie ticket cost $2.50. Now a movie ticket costs about $10.

Schach [20]

Percent change: (new value - old value)/old value * 100
((10-2.50)/2.50) = 3 * 100 = 300%
There is a 300% increase
