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

Seven pounds of grapes cost 10.43. How much would 3 pounds cost?
KiRa [710]
To answer this we will find the unit rate by dividing. Lets do it:-

10.43 ÷ 7 = 1.49
1 pound of grapes = $1.49

CHECK OUR WORK:-

1.49 × 7 =  10.43
we were RIGHT!!!

Now lets multiply to see how much 3 pounds would cost. 

1.49 × 3 = 4.47

CHECK OUR WORK:-

4.47 ÷ 3 = 1.49
We were RIGHT!!

So, 3 pounds of grapes cost $4.47. 

Hope i helped ya!!
