The difference between eight times a number and six more than three times the number. Please help find the equation and simplify

Rainbow [258]

Answer: x>1.2

Step-by-step explanation:

Let a number is x.

Hence,

$8x-6 > 3x\\\\8x-6-3x > 3x-3x\\\\5x-6 > 0\\\\5x-6+6 > 0+6\\\\5x > 6\\$

Divide both parts of the equation by 5:

$x > 1.2$

Express the rate 50 yards per minute in feet per second. Please answer with supporting work.

DiKsa [7]

First, multiply 50*3 to get the answer in feet which is 150 ft.

Then, divide 150 ft by 60 which would be 2.5 ft per second.

Pleaseeee help i don't understand how to do this

Answer:

$x=\frac{5}{k}$

Step-by-step explanation:

Given expression is,

$\text{log}_{3^k}243=x$

By using the law of logarithm,

$(3^k)^x=243$

$3^{kx}=243$

$3^{kx}=3^5$

By comparing exponents on both the sides of the equation,

$kx=5$

$x=\frac{5}{k}$

Therefore, $x=\frac{5}{k}$ will be the answer.

How do I find the ratio of this? It makes no sense to me

Volgvan

Answer:

$\frac{169}{289}$

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus

ratio of areas = 13² : 17² = 169 : 289 = $\frac{169}{289}$
