Answer:6.1

Step-by-step explanation: the equation is 6n=30.5+n. the first thing you you do is subtract n on both sides which would be 6n-n which gives you 5. the equation now is 5n=30.5. now what you do is divide 5 on both sides so it would be 30.5/5 and that gives you 6.1

Which pair shows equivalent expressions?

seraphim [82]

Given:

The pair of expressions in the options.

To find:

The pair that shows equivalent expressions.

Solution:

We have,

$2\left(\dfrac{2}{5}x+2\right)$

By using distributive property, we get

$2\left(\dfrac{2}{5}x+2\right)=2\left(\dfrac{2}{5}x\right)+2(2)$

$2\left(\dfrac{2}{5}x+2\right)=\dfrac{4}{5}x+4$

So, option A is incorrect and option B is correct.

We have,

$2\left(\dfrac{2}{5}x+4\right)$

By using distributive property, we get

$2\left(\dfrac{2}{5}x+4\right)=2\left(\dfrac{2}{5}x\right)+2(4)$

$2\left(\dfrac{2}{5}x+4\right)=\dfrac{4}{5}x+8$

So, options C and D both are incorrect.

Therefore, the correct option is B.
