Answer:

Step-by-step explanation:

It says n > 2. This means n is larger than 2. Therefore, it cannot be a correct solution.

If the symbol was n ≥ 2, then it would be a solution as that symbol means greater than or the same as 2.

Solving Exponential and Logarithmic Equations In Exercise, solve for x. 500(1.075)120x = 100.000

Volgvan

Answer:

The solution is:

$x = 0.61$

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

$500(1.075)^{120x} = 100000$

$(1.075)^{120x} = \frac{100000}{500}$

$(1.075)^{120x} = 200$

To find x, we have to apply log to both sides of the equality.

We also have that:

$\log{a^{x}} = x\log{a}$

$\log{(1.075)^{120x}} = \log{200}$

$120x\log{1.075} = 2.30$

$120x*0.03 = 2.30$

$3.77x = 2.30$

$x = \frac{2.30}{3.77}$

$x = 0.61$

Answer: 2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

A student's work to solve an equation is shown.

zvonat [6]

Answer:

the student solved the equation incorrectly because the original equation has one solution

Step-by-step explanation:

1/8(40x + 16) = 9x − 7(2x − 1) − 5

use the distributive property a(b + c) = ab + ac

(1/8)(40x) + (1/8)(16) = 9x + (-7)(2x) + (-7)(-1)

5x +2 = 9x − 14x + 7 − 5 combine like terms

5x + 2 = (9x - 14x) + (7 - 5)

here the student make mistake 9x - 14x = 5x

5x+2=-5x+2 add 5x to both sides and subtract 2 from both sides

5x + 5x + 2 - 2 = -5x + 5x + 2 - 2

10x = 0 divide both sides by 10

10x/10 = 0/10

x = 0
