Verdadero o falso a) al reducir a comun denominador las fracciones se sustituyen por otras equivalentes

alexgriva [62]

Answer:

Verdadero

Step-by-step explanation:

Verdadero, cuando cambias dos fracciones para darles un denominador comun la fraccion entera se sustituye para otra que tiene el mismo valor numerico que la original. Por ejemplo tenemos una fraccion 2/6 en la cual tenemos que cambiarle el denominador a uno comun con otra fraccion que es 18. Entonces sustituyemos la fraccion por la siguente fraccion 6/18. Esta nueva fraccion es equivalente a la original y los dos tienen el mismo valor numerico...

2 / 6 = 0.333

6 / 18 = 0.333

Visitors to a carnival can buy an unlimited-ride pass for $50 or an entrance-only pass for $20. In one day, 282 passes were sold

baherus [9]

Answer:

The unlimited-ride passes sold are equal to 168

Step-by-step explanation:

According to given scenario:

x = unlimited-ride passes

y = entrance-only pass

Given that:

50x + 20y = 10,680 -------- eq1

x + y = 282 ------------ eq2

From eq2:

x = 282 - y

Putting value of x in eq1:

50(282 - y) + 20y = 10,680

By simplifying:

14,100 - 50y + 20y = 10,680

14,100 - 30y = 10,680

30y = 14,100 - 10680

30y = 3,480

Dividing both sides by 30

y = 114

Now put value of y in eq2:

x + 114 = 282

x = 282 - 144

x = 168

So, the unlimited-ride passes sold are equal to 168

i hope it will help you!

Simplify completely

olasank [31]

Answer: D

<u>Step-by-step explanation:</u>

$\frac{x^{2}-15x+56} {x-7}$

First, factor the numerator (top):

x² - 15x + 56

∧

-1 -56

-2 -28

-4 -14

-7 -8 = -15

(x - 7)(x - 8)

Next, cancel out like terms from the numerator and denominator:

$\frac{(x-7)(x-8)} {x-7}$ = x - 8
