The answer is A. 42
Solution:
Let x= ones digit, y=tens digit
1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y
simplifying:
1st condition: 6x=3y
2nd condition: x=2
substituting x=2 to 6x=3y
<span>y=4</span>
Answer:
b =15
Step-by-step explanation:
We can use Pythagoras theorem to find b:
64 + 
= 289
64 + 225 = 289
64 + 
= 289
b = 15
hope this helps :) and sorry if not right
5+2=7, so the first blank is 2.
For the second blank, you just need two numbers in the box that when added, equals 7. (So 1,6 or 3,4)
Step-by-step explanation:
The numerical expression is:
(36 + 14) / (2 * 5).
Answer:
Step-by-step explanation:
x and 6
6^2 is 36
x^2 is still x^2
now we need to find the square root of their sum
square root of ( 36 + x^2 )
I'm not that sure about this one i think it might be more simplified
