Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system
If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
Answer:
Only 
is a perfect cube.
Step-by-step explanation:
is not a perfect cube because 8 is not a multiple of 3.
Now, is a perfect cube since 24 is a multiple of 3.
So, can be expressed as
Again, 
is not a perfect cube as 28 is not a multiple of 3.
And also 
is not a perfect cube as 64 is not a multiple of 3.
Therefore, only is a perfect cube. (Answer)
Step-by-step explanation:
Let x represent the missing sides measurement.
x+x+28=52
combine like terms
2x + 28 = 52
subtract 28 from both sides
2x + 28 = 52
- 28 - 28
2x = 24
divide both sides by 2
x = 12
plug it back in
one leg is 12 inches
the other leg is 40 inches
5(2x+4)=40 [distribute 5]
10x+20=40
10x=40-20 [move 20 to RHS and make it a negative]
10x=20 [divide both sides by 10]
x=2
