Answer:

No solution l

Solving steps:

=> R + 3= (r - 5)

=> $r - r + 3 = r - r - 5$

=> $3 = - 5$

Step 1: substract 3 from both side

=> $3 - 3 = - 5 - 3$

Step 2: Subtract 3 - 3 and -5 - 3

=> 0 = - 8

<h3>Therefore this solution that have no solution </h3><h3>Good luck and enjoy ^_^</h3>

Answer:

no solutions

Step-by-step explanation:

Solving

Step 1: Subtract 3 from both sides.

$r+3-r=r-5-r$
$3=-5$

Step 2: Subtract 3 from both sides.

$3-3=-5-3$
$0\neq -8$

Therefore, there are no solutions to this equation.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she wo

Elodia [21]

Answer:

She will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.

Step-by-step explanation:

Given:

Alondra received a 14% hourly raise, but the number of hours worked decreased by 7.5%. If her wage was $10.50 an hour and she worked 40 hours per week before the changes.

Now, to find money she will earn in one week after the changes.

Her wage was = $10.50.

She worked per week = 40 hours.

So, her salary before changes:

$10.50\times 40\\\\=\$420.$

Thus, the salary per week before changes is $420.

Now, to get her salary after 14% hourly raise:

$10.50+14\%\ of\ 10.50\\\\=10.50+\frac{14}{100} \times 10.50\\\\=10.50+1.47\\\\=11.97$

Salary after hourly raise = $11.97 per hour.

Then, to get the number of hours worked decreased by 7.5%:

$40-7.5\%\ of\ 40\\\\=40-\frac{7.5}{100} \times 40\\\\=40-3\\\\=37.$

Number of hours per week after hours of worked decreased = 37 hours.

Now, to get the salary after changes:

Salary after hourly raise × number of hours per week after hours of worked decreased

$=11.97\times 37$

$=\$442.89.$

Salary after changes in one week = $442.89.

As, the previous salary was $420 in one week. 

And after changes this salary is $442.89 in one week which is more than previous. 

Therefore, she will earn $442.89 in one week after the changes.

And this is more than her previous weekly earnings.

Ming says that 0.24 > 1/4 because 0.24 = 2/4. Which best explains Ming's error?

Iteru [2.4K]

Because 0.24 = 24/100 and 1/4= 25/100 and 0.24 = 24/100 and 2/4/ 50/100=2
and so she missed calcuated and so its wrong.

the correct answer is 0.24<2/4 then 0.24=/2/4
