Como las fracciones representan números reales se mantiene la jerarquía de las operaciones de éstos.
Si no hay paréntesis, ni potencia y radicales, la mayor jerarquía la tiene la multiplicación o división que está más a la izquierda.
Se puede proceder eliminando una por una, de izquierda a derecha, todas las multiplicaciones y divisiones.

In parallelogram WXYZ, what is CY?<br> 11 ft<br> 15 ft<br> 21 ft<br> 23 ft

erastovalidia [21]

Answer:

15 ft

Step-by-step explanation:

In a parallelogram the diagonals bisects each other

So WC= CY

$x+4=2x-7$ solve the equation for x

Subtract x from both sides

$x-x+4=2x-x-7$

$4=x-7$

Now we add 7 on both sides

$4+7=x-7+7$

x=11

Now we need to find CY

$CY= 2x-7$

Plug in 11 for x

$CY= 2(11)-7=22-7= 15$

In 7th grade there are 58 students with red-hair and 609 students with another color hair. The numbers of red-haired students in

mr_godi [17]

In 7th grade:

red-hair students =58

another color hair students =609

In 8th grade:

red-hair students =60

Let's assume

another color hair students =x

now, we are given

The numbers of red-haired students in 8th grade are proportional to the numbers in 7th

so,

$\frac{60}{58} =\frac{x}{609}$

now, we can solve for x

we get

$x=609*\frac{60}{58}$

we get

$x=630$

so, students have another color hair in 8th grade is 630.........Answer
