Answer:
Step-by-step explanation:
- log8(216) + [log(42) - log(6)] ÷ log(49) =
- log (216)/ log (8) + [log (7) + log (6) - log (6)] ÷ 2 log (7) =
- 3 log (3) log (2) / 3 log (2) + log (7) / 2 log (7) =
- 3 log (3) + 1/2

Answer:
x =30
Step-by-step explanation:
in order to evaluate the solution 4/5=20/(x-5)?
solution
the first step to take is to cross multiply
4/5=20/(x-5)
we have,
5 x 20 = 4 ( x -5)
100 = 4x - 20
combine the like terms
100+20 = 4x
120 = 4x
divide both sides by the coefficient of x
120/4 = 4x/4
30 = x
x =30
therefore the value of x in the expression 4/5=20/(x-5)? is 30
(x-3)/2 i believe, good luck
Answer: B
Step-by-step explanation:
Substitute x = -3 into the equation.
y is equal to 3^-3 = 1/27
So the answer is B
