Answer:
15
Step-by-step explanation:
Because x=y÷7
i.e,105÷7=15
8 x 5 x 4 = 160m^3
to find the volume of a cube its V= W x H x L
(5, 90)
You can solve both equations for y and then set equal to each other. Then use the quadratic equation to solve for x
Base six and greater would make 4025 a legitimate numeral.
Legitimate number in which bases a number is legitimate by comparing the largest digit with the base number. If the largest digit is less than the base number, it is a legitimate number.
We have number 4025 .So, here largest digit is 5.
As 4025 to be the Legitimate numeral ,the base number should be greater than the largest digit of the numeral. So the base number should be greater than 5 .
Therefore, any base of 6 or higher would make 4025 a legitimate numeral.

Answer:
The answer is D(20)
Step-by-step explanation:
I don't know the exact algebraic explanation, however, this is how I did it.
If you divide the second equation into seperate twos, you will get 2*2*2*2*2*2 = 
Therefore, 
meaning that x is equal to 6. Now The next bit is trial and error, 20-6=14. 
Last thing to do is to add x+y=6+14. That is why the answer is 20.
If you wait a bit longer, someone will probably have a more algebraic explanation, however, you stated you only needed the answer so I hope this helped.
