To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

\frac{2}{x+2}+\frac{1}{5}=\frac{6}{x+5}

2. You need to sum the fractions located on the left member, as following:

\frac{10+(x+2)}{5(x+2)}=\frac{6}{x+5}

x=(12+x)(x+5)=6(5x+10)

3. Simplify it and you will obtain a quadratic equation. Solve it by factor out x:

x^{2} -13x=0\\ x(x-13)=0\\ x=0; x=13

Therefore, the answer is: x=0; x=13

A 33 gram sample of a substance that's
Mazyrski [523]

9514 1404 393

Answer:

  6.2

Step-by-step explanation:

We presume your "k-value" is the k in the exponential decay term ...

  e^(-kt) . . . where t is the number of time units

This is 1/2 when ...

  ln(1/2) = -kt

  t = ln(1/2)/(-k) = ln(2)/k

  t = 0.69315/0.1124 ≈ 6.2

The half life is about 6.2 time units.

3.5 hours:$10 1/2 hour:$1.25. What is the unit rate in dollars per hour for each company?
Rasek [7]

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).

Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.

The unit rate is 2,86:2,50

Please help I don’t understand
Anit [1.1K]

Answer:

$30 per Ticket

Step-by-step explanation:

There are 3 friends coming along you so that means you have to divide one number by 3. You have a $20 coupon so that meant you had to subtract 20 from 120. <em><u>20-120=100.</u></em>

Now, you have to divide 100 by the 3 friends then add 5 to each number.

<em><u>3 divided by 100=25+5=30</u></em>

<u>So, $30 is your answer</u>
