<span>Cada goma de borrar es $ 5. Primero restar el precio de las revistas ($ 5) del dinero que gastó. Ella ahora tiene $ 20. Luego divida eso entre cuantos borradores compró (4). 20 dividido por 4 es 5. Cada borrador fue de $ 5. ¡Espero que la traducción tenga sentido !!</span>
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let and be, respectively, the number of girls and boys.
We know that (the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that (there are 61 students in total).
So, we have the system
We can use the first equation to substitute in the second
And then solve for :
For the second problem, let and be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
Answer:
Step-by-step explanation:
Solve the logarithm function.
Put the logarithm function on one side of the equation and x on the other.
<h3>log x + log8=2</h3>
<u>First, subtract by log₁₀(8) from both sides.</u>
<u>Solve.</u>
- <u>Therefore, the correct answer is x=25/2=12.5.</u>
I hope this helps you! Let me know if my answer is wrong or not.
Answer:
10.67
Step-by-step explanation:
The 10 stays as it is. The 2/3 is approximated by 0.67 (to the nearest hundredth). Thus, we have 10.67 to the nearest hundredth.
