Alright, lets get started.
If Matthew wants to complete packages at an average rate of at least 39 packages per hour.
And they worked 4 hrs only due to picnic, yesterday, it means they have to make 
packages.
But they made only 112 packages means they are short of 
packages.
Suppose they are working today t hrs, and his department will complete 43 packages per hour today.
It means they are going to make 43 t packages today.
This 43 t packages includes those 44 too , which they are short of yesterday due to picnic.
So, average will be
(39 average given in question)
Cross multiplying
Adding 44 in both sides
Subtracting 39 t in both sides
Dividing 4 in both sides
t = 11 hrs
Hence they have to woth 11 hrs today : Answer
Hope it will help :)
<span>12x = 7y-10y
12x = -3y
-4x= y
y = -4x</span>
We have been given that the slope-intercept form of a linear equation is 
, where x and y are coordinates of an ordered pair, m is the slope of the line, and b is where the line crosses the y-axis. We are asked to solve the equation for slope.
First of all, we will subtract 'b'from both sides.
Let us switch the sides:
Now we will divide both sides by x.
Therefore, the value of m is 
.
Answer:
Al comienzo Juana tiene 28 libras de azúcar.
Ella hace 6 paquetes de 2.5kg cada paquete.
Entonces, entre los 6 paquetes, hay:
6*2.5kg = 15kg de azúcar.
Ahora el problema es que tenemos dos unidades distintas, kilogramos y libras.
Aca podemos usar la relación:
1k = 2.2lb.
Entonces 15kg de azúcar son 15 veces 2.2 libras:
15kg = 15*2.2lb = 33lb.
Esto nos da mas de lo que hay originalmente en el costal.
Ahora si lo pensamos como:
Solo vendió 5 paquetes de 2.5kg, entonces el sobrante queda en el costal inicial:
5*2.5kg = 12.5kg
De vuelta, 1kg = 2.2lb
12.5kg = 12.5*2.2lb = 27.5lb
En este caso hay un sobrante de:
28lb - 27.5lb = 0.5lb
