Answer. 0.125
Answer:
Q = 52.5
Step-by-step explanation:
given P is directly proportional to Q then the equation relating them is
P = kQ ← k is the constant of proportion
to find k use the condition Q = 30 when P = 40 , then
40 = 30k ( divide both sides by 30 )
=
= k
P =
Q ← equation of proportion
when P = 70 , then
70 =
Q ( multiply both sides by 3 to clear the fraction )
210 = 4Q ( divide both sides by 4 )
52.5 = Q
Answer:
x = 3
Step-by-step explanation:
3^(5x - 9) = (1/27)^(2x-8)
3^(5x - 9) =(3^-3)^(2x-8)
3^(5x - 9) = 3^(-6x + 24)
So now you can solve for x since you have same base 3
5x - 9 = -6x + 24
11x = 33
x = 3
