Teresa wrote this expression to describe the total distance she was going to swim during two swim classes.

1 answer:

5 0

I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct

A store advertises 15% off an item that regularly sells for $300.

Ilia_Sergeevich [38]

Regular price = 300

Sale = 15%

Price after sale

= 300 - 15%(300)

= 300 - 15/100 x 300

= 300 - 15 x 3

= 300 - 45

= 255

una fracion reducicion a su minima expresion en igual a 1/8 . si la suma de sus terminos es 72. hallar la diferencia entre ellos

Mandarinka [93]

La diferencia entre el denominador y el númerador de la fracción es:

64 - 8 = 56.

<h3>¿Como encontrar la fracción?</h3>

Tendremos una fracción de la forma:

$\frac{a}{b}$

Tal que:

$\frac{a}{b} = \frac{1}{8}$

$a + b = 72$

Eso es un sistema de ecuaciones

Primero, podemos reescribir la primer ecuación como:

$8a = b$

Ahora podemos reemplazar "b" en la segunda ecuación por "8a", así obtenemos:

$a + 8a = 72\\\\9a = 72\\\\a = 72/9 = 8$

Ahora podemos obtener el valor de b:

$b = 8a = 8*8 = 64$

La diferencia entre a y b es:

$b - a = 64 - 8 = 56$

Answer: 68 cubic inches

Step-by-step explanation:

basically the volume of the rectangular prism would be 2 x 2 x 14, so that's 56. Then the area of the triangular prism is 3 x 2 x 2, divided by 2, which is 6. There are two triangular prisms so that' 12. 56 + 12 is 68. That's the answer
