(1.3x + 2.4) - (6.1x - 3.2)

Mathematics
1 answer:

4 0

Answer: \frac{4}{5}(7-6x)

Step-by-step explanation:

We have the following expression:

(1.3x+2.4)-(6.1x-3.2)

Here we have to group similar terms, but firstly we have to solve what is inside the second parenthesis according to the rules of algebraic operations (equal signs give as a result a positive sing and different sings gives as a result a negative sing):

1.3x+2.4-6.1x+3.2

5.6-4.8x

This expression can be written as:

\frac{28}{5}-\frac{24}{5}x

Applying common factor \frac{4}{5}:

\frac{4}{5}(7-6x) This is the result

Starting time 2:15 am elapsed time 45 minutes
AveGali [126]
One hour = 60 minutes
60-15=45 so I would just add your 45 minutes to your 2:15
2:15+:45= 3:00

 so your answer will be 3:00    :)

Answer: $28.30✔️

Step-by-step explanation:

Let C = cost before tax

Cell phone costs = C + C·6% = $30

C(1 + 0.06) = $30

C = $30/1.06 = $28.30

Answer: $28.30✔️

<h3> Verify </h3>

Cell phone after tax = $28.30 + $28.30·6/100 = $28.30 + $1.70 = $30✔️
