Y is common to both top and bottom of the fraction so can be cancelled out ( because y / y = 1)
so the answer is 5/23
Answer:
-10(-h-9)=18
Step-by-step explanation:
-10(-h-9)=18
10h+90=18
10h=-72
h=-7.2
The answer for this would be x=12
Answer:
2.326
Step-by-step explanation:
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))
