Answer: It took 18 Months for Michelle to collect 59 dolls.
Explanation:
First, let’s right an equation for this. Michelle started with 5 dolls in a bar collection (I have no clue what that is but i’ll roll with it), and each month she bought 3 more, so 5 dolls plus the 3 dolls per month equals 59 at some point.
5 dolls + 3 dolls per month = 59 dolls
OR
5 + 3m = 59
The point of this question is to find how many months (m) it took in order to get to 59 dolls and there’s multiple ways you can do this:
1) just plug in random numbers into m to see how long it takes to get to 59 [this option might take a while]
2) Try to isolate m (get every number out of the equation) to find out the value of m. [I’m most familiar with this way]
First, subtract 5 from 5 in the equation in order to get rid of it, since we’re trying to get all whole numbers out of the equation and only have m left. You subtract 5 from 59 since the equal sign is kind of like a mirrror, whatever you do to one side you have to do to the other. So, 5-5 is 0, and 59- is 54.
Now you’re left with 3m=54. In order to isolate the m, divide 3 by 3 to get rid of the 3, then divide 54 by 3, which is 18.
In order to check your work, plug 18 into m just to see if it works or not:
5+3m=59 —-> 5+ 3(18)= 59
3 times 18 is 54, plus 5 is 59. So, Mi hells took 18 months to collect her 59 dolls. Hope this helped!
La franja amarilla del rectángulo tiene un área de 30 centímetros cuadrados.
<h3>¿Cuál es el área de la franja amarilla del rectángulo?</h3>
En este problema tenemos un rectángulo formado por dos cuadrados que se traslapan uno al otro. La franja amarilla es el área en la que los cuadrados se traslapan. La anchura del rectángulo es descrita por la siguiente ecuación:
(10 - x) + 2 · x = 17
Donde x se mide en centímetros.
A continuación, despejamos x en la ecuación descrita:
10 + x = 17
x = 7
Ahora, el área de la franja amarilla se determina mediante la fórmula de area de un rectángulo:
A = b · h
Donde:
- b - Base del rectángulo, en centímetros.
- h - Altura del rectángulo, en centímetros.
- A - Área del rectángulo, en centímetros cuadrados.
A = (10 - 7) · 10
A = 3 · 10
A = 30
El área de la franja amarilla del rectángulo es igual a 30 centímetros cuadrados.

Answer:
Rewrite the equation as x+xyz=wx+xyz=w.
x+xyz=wx+xyz=w
Subtract xx from both sides of the equation.
xyz=w−xxyz=w-x
Divide each term by xzxz and simplif
