-20+1= -19
-19/2= -9.5
Check:
-9.5x2= -19
-19-1= -20
2^2x=5^x−1
Take the log pf both sides:
ln(2^2x) = ln(5^x-1)
Expand the logs by pulling the exponents out:
2xln(2) = (x-1)ln(5)
Simpligy the right side:
2xln(2) = ln(5)x - ln(5)
Now solve for x:
Subtract ln(5)x from both sides:
2xln(2) - ln(5)x = -ln(5)
Factor x out of 2xln(2)-ln(5)x
x(2ln(2) - ln(5)) = -ln(5)
Divide both sides by (2ln(2) - ln(5))
X = - ln(5) / (2ln(2) - ln(5))
Answer:
The snowiest city receive 347.7 inches on average each year.
Step-by-step explanation:
We want to find the amount of snow the snowiest city receives on average every year, "x". It is known that this city receives 113.9 more inches than the second snowiest, which receives 223.8 inches on average every year. Therefore, the expression for "x" is:
The snowiest city receive 347.7 inches on average each year.
Answer: 2 d - 3
Step-by-step explanation:
Here, the number of dozen eggs in one refrigerator = d
According to the question,
There are 3 fewer dozen eggs in another refrigerator.
⇒ The number of eggs in another refrigerator = d - 3
Thus, the total dozen of eggs in both refrigerator = the number of dozen eggs in first refrigerator + the number of dozen eggs in second refrigerator
= d + d - 3
= 2 d - 3
Which is the required expression.
