Solve<br>0.9(7x + 14) = 1.5 - (x + 2)

Triss [41]

$\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)$

$\\ \sf\longmapsto 6.3x+12.6=1.5-x-2$

$\\ \sf\longmapsto 63x+12.6=-x-0.5$

$\\ \sf\longmapsto 63x+x=-0.5-12.6$

$\\ \sf\longmapsto 64x=-13.1$

$\\ \sf\longmapsto x=\dfrac{-13.1}{64}$

$\\ \sf\longmapsto x=0.2$

Pedro le dice a María si cambias los billetes de 10 € que tienes por billetes de 5 € y los billetes de 5 € por billetes de 10 €

Bad White [126]

Answer: Maria has 10 bills of 5€ and 10 bills of 10€.

She has a total of 150€.

Step-by-step explanation:

Let be "f" the number of 5€ bills that Maria has and "t" the number of 10€ bills that Maria has.

Set up a system of equations:

$\left \{ {{f+t=20} \atop {5f+10t=10f+5t}} \right.$

Use the Substitution method to solve the system of equations:

1. Solve for "f" from the first equation:

$f=20-t$

2. Substitute the equation obtained into the second equation and solve for "t".

Then:

$5(20-t)+10t=10(20-t)+5t\\\\100-5t+10t=200-10t+5t\\\\20t-10t=100\\\\t=\frac{100}{10}\\\\t=10$

3. Substitute the value of "t" into the equation $f=20-t$ and evaluate:

$f=20-10\\\\f=10$

Therefore, Maria has 10 bills of 5€ and 10 bills of 10 €.

So the total amount of money she has, is:

$Total=10(5)+10(10)=150$

She has a total of 150€.

Ugo [173]

Let be x the number of rows
there are 1200 seats, and each row has 20seats
so 20x=1200, so x= 60, there are 60 rows in the theater
