Best has knitted 5/8 of the scarf she is making has she needed more than one half of the scarf can't find the equivalent fractio

BabaBlast [244]

To compare 5/8 and 1/2, you will need to create fractions that have the same denominator. 1/2 is the same as 4/8.

5/8 is greater than 4/8, so she had knitted more than 1/2.

En un examen de admisión de 120 preguntas, cada respuesta correcta vale 2 puntos y por cada incorrecta se quita medio punto. Un

padilas [110]

Answer:

Respondió mal 64 preguntas.

Step-by-step explanation:

De acuerdo a la información proporcionada puedes plantear las siguientes ecuaciones:

x+y=120 (1)

2x-0,5y=80 (2)

x es el número de preguntas correctas

y es el numero de preguntas incorrectas

Primero debes despejar "x" en (1):

x=120-y (3)

Después, debes reemplazar (3) en (2):

2(120-y)-0,5y=80

240-2y-0,5y=80

240-80=2,5y

160=2,5y

y=160/2,5

y=64

Ahora puedes reemplazar el valor de "y" en (3) para encontrar el valor de "x":

x=120-y

x=120-64

x=56

De acuerdo a esto, la respuesta es que el postulante respondió mal 64 preguntas.

timofeeve [1]

Answer:

Store 2

Step-by-step explanation:

Given

1. $4.50 for 5 pounds

2. $1/5 for 1/3 pounds

3. $4.00 for 5 pounds

Required

Determine the store with the lowest unit rate

To do this, we simply divide the price by the weights in each store

For Store 1:

$Unit\ Rate = \frac{\$4.50}{5\ lb}$

$Unit\ Rate = \$0.9/lb$

For Store 2:

$Unit\ Rate = \frac{\$1/5}{1/3\ lb}$

$Unit\ Rate = \$0.6/lb$

For Store 3:

$Unit\ Rate = \frac{\$4.00}{5\ lb}$

$Unit\ Rate = \$0.8/lb$

<em>Comparing the unit rates of the three stores, we can conclude that store 2 offers the least unit rate</em>
