Answer:
Below in bold
Step-.by-step explanation:
1. 5 ^(3+4) = 5^7.
2. 2^(8*2) = 2^16.
3. 1.
4. n^11
5. 8^(7-2) = 8^5.
6. 1 / 3^4.
7. 7.
8. 8.
9. 5^4.
10. 81.
Here the question is simple.
All because, we only need to find the value of x.
We are given two equations.
5x + 6 = 10 and 10x + 3 =?
So, we will find the the value of x in the first equation, so that we can substitute the value of x in the second one and there we are with the answer.
5x + 6 = 10
For finding the value of x, all we have to do is,
Transpose the number 6 to 10
Therefore. 5x = 10 - 6 ( Take the equal sign as The Magic Bridge on which if anyone crosses it , will change its sign.)
So we have,
5x = 4
So x = 4/5 ( Multiplication will change to division after crossing the equal sign)
( Doubtful? Substitute the value of x and try!)
Now that we got the value of x,
We can just simply substitute the value of x in the second equation.
10x + 3 = ?
x = 4/5
10*4/5 +3 => 5 and 10 get canceled to 2 at the numerator.
By normal multiplication and then addition, we will get,
8 + 3 = 11
Hope this helps!!!! :)
Answer:
Step-by-step explanation:The formula is the long root of (x2-x1)² + (y2-y1)², you have -1 to be the value of x2 and -4 is the value of x1 while 4 is the value of y2 and -8 is the value of y1 therefore (-1+4)²+(4+8)² = (3)²+(12)²= √9+12=√153
Answer:
102°C
Step-by-step explanation:
The chemical compound has a freezing point of -5°C and a boiling point of 97°C.
Since the freezing point is the lower temperature and the boiling point is the higher temperature, the difference between the two temperatures will be subtraction of the freezing point from the boiling point. That is:
97 - (-5) = 97 + 5 = 102°C
The difference between the freezing point and the boiling point is 102°C
