Answer:
The value of X in the equation 3X (-1) / 9Y equals 18 when Y equal 27 is 1458.33
Step-by-step explanation:
is a polinomial equation A
if the value of Y = 27
put this value of Y in the equation A


243 will be taken to right hand side and as per rule will be multiplied by 18


1 will be taken to right hand side and added as per rule

3 wil be taken on right hand side and divided as per rule

So the value of X if Y = 27 is 1458.33

I'll guess P is the perimeter, the sum of the edge lengths.
In centimeters
I get 4 + 4 + 4 + 4 for the sides of the isoscles triangles
5 + 5 + 2.8 + 2.8 for the rectangular base
5 for the apex/top
P = 4+4+4+4+5+5+2.8+2.8+5=36.6 cm
Not sure why the exact answer isn't there, but first choice seem best.
Get packing.
Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
The answer would be the veggie sandwich.
Hope that helps! :)
