Answer:
-1
Step-by-step explanation:
5^(3b-1) = 5^(b-3)
3b-1=b-3 / +1 -b
2b = -2
b = -1
Answer: Equivalent expressions
14⋅x or 6+8x
Answer:
81
Step-by-step explanation:
2(x - 25) = 112
x - 25 = 112/2
x - 25 = 56
x = 56 + 25
x = 81
Answer:
n = -14
Step-by-step explanation:
Let us try to solve this equation for n;
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 + n
3x - 3x -8 - 6 = n
-14 = n
The value of n = -14
This value is the value of the equation that will have no solution.
To know if we are correct, let us input this value into the expression
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 -14
Collect like terms;
3x - 3x = 8 + 6 - 14
0 = 0
All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.
8 - 15 = -7
It would be -7<span>°C at midnight. I hoped this helped! :)</span>
