Xlog5 - log125 = 0 solve for x. Asking for step by step answer.

1 answer:

7 0

Step-by-step explanation:

$x log(5) - log(125) = 0 \\ log( {5}^{x} ) - log(125) = 0 \\ log( \frac{5x}{125} ) = 0 \\ \frac{ {5}^{x} }{125} = 1 \\ {5}^{x} = 125 \\$

$log( {5}^{x} ) = log(125) \\ x log(5) = log(125) \\ x = \frac{ log(125) }{ log(5) } = 3$

For all values of x and y, which expression is equivalent to 8x + 6y? A) 2(4x + 3y) B) 2x + 3y C) 3(4x + 2y) D) 4(2x + 3y)

Reika [66]

The answer would be 2(4x + 3y) cause the 2 gets multiplied by the numbers in the parentheses so 2x4x = 8x and 2x 3y = 6y

Rico walked for 3/10 mile. Then he walked for 24/100 mile. How far did he walk in all?

grigory [225]

First, Rico walked for 3/10 of a mile which is 30/100 of a mile.
Hen, Rico walked for 24/100 of a mile.
Then you add 24/100 and 30/100. 24+30/100 which is 54/100.
Answer=54/100 of a mile

Answer:

$\large\boxed{x\in(-\infty,\ 8)\ \cup\ (10,\ \infty)}$

Step-by-step explanation:

$-3+9x>87\qquad\text{add 3 to both sides}\\\\9x>90\qquad\text{divide both sides by 9}\\\\\boxed{x>10}\to(1)\\\\-x-9>-17\qquad\text{add 9 to both sides}\\\\-x>-8\qquad\text{change the signs}\\\\\boxed{x10\ or\ x$
