yes

Step-by-step explanation:

A number or an integer that divides 8 exactly without leaving a remainder, then the number is a factor of 8. As the number 8 is an even composite number, it has more than two factors. Thus, the factors of 8 are 1, 2, 4 and 8.

Una diseñadora de modas que confecciona trajes de noche, tarda 3 horas en cortar y 2 horas en coser cada vestido de fiesta. Para

ella [17]

For this case we define the following variables:

x: Number of party dresses

y: Number of suits

You have 30 hours per week to cut, that is, the first equation is given by:

$3x + 3y = 30\\$

It is also known that 25 hours per week are available for sewing, that is:

$2x + 3y = 25\\$

It has a system of two equations with two unknowns, solving we have:

$3x + 3y = 30\\\\2x + 3y = 25\\$

Multiplying the second equation by -1:

$3x + 3y = 30\\\\-2x-3y = -25\\$

Adding up:

$x + 0 = 5\\\\x = 5\\$

Substituting x in the first equation:

$3 * 5 + 3y = 30\\\\15 + 3y = 30\\$

Clearing and:

$3y = 30-15\\\\3y = 15\\$

$y = \frac{15}{3}\\\\y = 5\\$

Thus, per week, the designer can produce 5 party dresses and 5 suits working at her maximum capacity.

Answer:

5 Party dresses

5 Suits
