Answer:
Step-by-step explanation:
Let's call the "positive real number" X.
Basically, the question is a riddle asking for the "solution" to 14x+240=x²
Figure that out, and
The answer is 24.
x-5>-2
x> -5+2
X>3
Answer is: {x | x R, x > 3}
Step-by-step explanation:
5^(3b−1) = 5^(b−3)
Since the bases are equal, the exponents must also be equal.
3b − 1 = b − 3
2b = -2
b = -1
Answer:
y=3
Step-by-step explanation:
y + 3 = -y + 9
y + y = 9 - 3
2*y = 6
y = 6/2
y = 3
